While working in Excel, we often need to draw circles in our worksheets. In Excel, there is no specific command or option to draw a circle. But Excel allows us to draw a circle by tweaking some of the built-in commands. We can also specify the radius of the circle. In this article, we will discuss three efficient approaches to draw a circle with specific radius in Excel. So, letâ€™s start this article and explore these approaches.

## How to Draw a Circle with Specific Radius in Excel: 3 Simple Methods

In this section of the article, we will learn **three **simple methods to draw a circle with specific radius in Excel. Not to mention, we used the Microsoft Excel 365 version for this article; however, you can use any version according to your preference.

### 1. Utilizing Parametric Equation of Circle

Utilizing the **Parametric Equation** of circle is one of the most effective ways to draw a circle with specific radius in Excel. First, letâ€™s know about the parametric equation of circle.

The parametric equations of a circle are:

*x = r cos(t)Â *

*y = r sin(t)*

Where, **x**, and **y **are the** coordinate points**, **r **is the **radius of the circle**, and **t **is the **angle **subtended by the radius at the center of the circle.

So, if we find the **x**, and **y **values and plot them in an **Excel Scatter Chart**, we will get a circle. Letâ€™s say, we have the following dataset with values of different **Angles**. There are more cells at the bottom of this image. Now, letâ€™s follow the steps mentioned below to draw a circle with specific radius in Excel.

- Firstly, create a table as shown in the image below.

- After that, enter the following formula in cell
**C5**.

`=$F$5*COS(B5)`

Here, cell **F5 **represents the **Radius** of the circle, and cell **B5 **refers to the first cell of the **Angle **column. Then, the **COS function** will return the **x value** of the coordinate.

- Then, press
**ENTER**.

As a result, you will have the following output in cell **C5 **as shown in the following picture.

- Following that, use the
**AutoFill**feature to get the rest of the**x values**.

- Now, apply the following formula in cell
**D5**.

`=$F$5*SIN(B5)`

Here, cell **F5 **indicates the **Radius** of the circle, and cell **B5 **represents the first cell of the **Angle **column. Then, the **SIN function** will return the **y value** of the coordinate.

- After that, hit
**ENTER**.

Subsequently, you will have the corresponding** y values** in cell **D5**.

- Afterward, use the
**AutoFill**option to get the remaining**y values**as shown in the following picture.

- Following that, select the cells of the columns named
**R*COS(Angle)**, and**R*SIN(Angle)**. - Then, go to the
**Insert**tab from**Ribbon**. - After that, click on the
**Insert Scatter (X,Y) or Bubble Chart**option from the**Charts**group. - Now, select the
**Scatter with Smooth Lines**option from the drop-down.

As a result, you will have the following chart on your worksheet.

- At this stage, you can
**customize the scatter chart**and get the following final output.

You can see that we have created a circle with a radius of **10**, using the parametric equations of the circle.

### 2. Using Shapes Option

Using the **Shapes **option is one of the easiest ways to draw a circle with a specific radius in Excel. Letâ€™s use the instructions outlined below to do this.

__Steps:__

- Firstly, go to the
**Insert**tab from**Ribbon**. - After that, click on the
**Shapes**option from the**Illustrations**group.

- Now, choose the
**Oval**option from the drop-down as marked in the image below.

- Following that, press and hold the
**SHIFT**key from your keyboard. - Subsequently, draw a circle on your worksheet.

- After that, right-click at any point inside the circle.
- Then, choose the
**Format Shape**option.

As a result, the **Format Shape** dialog box will appear on your worksheet.

- Now, in the
**Format Shape**dialog box, select the**No Fill**option under the**Fill**section. - Following that, choose the
**Solid line**option under the**Line**section. - Next, increase the
**Width**to**2 pt**.

- After that, go to the
**Size & Properties**tab in the**Format Shape**dialogue box. - Now, insert the
**Height**. It should be**double**the radius of the circle. For example, if you want a circle of radius**5**, then the**Height**will be**10**. In this case, we used**2**as the**Height**. - Then, insert the
**Width**. It should be the same as the**Height**.

- Finally, close the
**Format Shape**dialog box and you will get a circle with a specific radius as demonstrated in the following image.

### 3. Applying VBA Macro Feature

Applying the **VBA Macro** option is another smart way to draw a circle with a specific radius in Excel. In the following section, we will discuss the detailed steps to do this, along with the respective **VBA code**.

__Steps:__

- Firstly, go to the
**Developer**tab from**Ribbon**. - Then, click on the
**Visual Basic**option from the**Code**group.

As a result, the **Microsoft Visual Basic** window will open on your worksheet.

- Now in the
**Microsoft Visual Basic**window, go to the**Insert**tab. - Then, choose the
**Module**option from the drop-down.

- Following that, write the following code in the newly created
**Module**.

```
Sub CircleGenerator()
Dim rad As Long
rad = InputBox("Insert the radius of the circle")
With ActiveSheet.Shapes.AddShape(msoShapeOval, 200, 200, rad * 2, rad * 2)
.Name = "CIRCLE"
.Fill.ForeColor.RGB = vbWhite
.Line.Transparency = 0
.Placement = 1
End With
End Sub
```

**Code Breakdown**

- Firstly, we created a sub-procedure called
**CircleGenerator**. - After that, we declared a variable named
**rad**and defined it as**Long**. - Then, we took the value of the variable
**rad**, by using an**InputBox**statement. - Following that, we used a
**With**statement to specify the characteristics of the circle. - Subsequently, we ended the
**With**statement. - Lastly, we terminated the sub-procedure.

- After writing the code, click on the
**Save**option.

- Now, use the keyboard shortcut
**ALT + F11**and you will be redirected to the worksheet. - Then, press
**ALT + F8**to open the**Macro**dialogue box as shown in the following picture.

- Now, in the
**Macro**dialogue box, select the**CircleGenerator**option. - After that, click on
**Run**.

As a result, a pop-up window will appear as shown in the following picture.

- Now, insert the
**radius**of the circle as you need. Here, we inserted**30**as the**radius**. - Subsequently, click
**OK**.

Consequently, you will have a circle with a **radius **of **30** as demonstrated in the following picture.

## How to Draw an Arc in Excel

In this section of the article, we will learn how we can draw an **arc **in Excel. Drawing an arc is almost similar to the steps of drawing a circle. An arc is only a section of a circle. So, to draw an arc, we only need a section of the dataset that we used in the first method. Now, letâ€™s follow the steps mentioned below to do this.

__Steps:__

- Firstly, create a table as shown in the following image. Here, we specified the radius of the arc as
**10**units.

- After that,
**follow the steps mentioned in the first method**and you will get an**arc**with a radius of**10**as shown in the image below.
