How to Convert Diameter to Circumference?

The circumference of a circle is the length of its outer boundary. The diameter of a circle is a straight line joining a point from one end of the circle to a point on the other end of the circle, passing through the center.

The formula for the circumference of a circle when its diameter is known is:  Circumference = п × Diameter. Here, п is a constant which is equal to 3.14 or 22/7.

Let's go through the following example to learn how to calculate the circumference of a circle when the diameter is given.

Solved Example:

The length of the diameter of a circle is 14 units. Find the circumference of the circle. Use (п = 22/7)

Solution: 

We have diameter = 14 units. We will use the formula of the Circumference: Circumference = п × Diameter

= (22/7) × 14

= 22 × 2

= 44 units

Now, try the calculator and find the circumference of the circle for the following diameters:

• Diameter = 80 units
• Diameter = 170 units
