How to find perimeter of a circle using radius?

Since the perimeter of a circle is dependent on the diameter, you can use the information in the diameter table to calculate the perimeter of a circle. The perimeter of a circle is equal to the length of all the sides of a circle multiplied by Pi. This is equal to P = Pi d. So, if you know the diameter of a circle, you can use the equation to find its perimeter.

How to find perimeter of a circle using radius and area?

We can find the perimeter of a circle using area. Area of a circle is equal to πr^2, where r is the radius of the circle. Hence, the perimeter of a circle is equal to πr or P = πr. These two approaches are equivalent, just use the one that makes the most sense to you.

How to find perimeter of a circle using area and radius?

The sum of the areas of a circle is equal to pi times its circumference. Therefore, to find the perimeter of a circle, you can use the circumference value you found earlier to find its area.

How to find the perimeter of a circle using radius and diameter?

To find the perimeter of a circle using the radius and diameter, just subtract the diameter from the circumference. The result will be the perimeter of the circle. But the answer is not a number! To convert the perimeter to a number, you have to multiply the perimeter by the circumference of a circle.

How to find perimeter of a circle using radius and diameter?

Most of the secondary school and middle school geometry problems in India contain the circumference of a circle as one of the questions. And if you are preparing for competitive exams like UPSC CPT, State PSC or SSC exams, you will definitely be asked to solve perimeter of a circle questions. In this article, I will cover the methods to calculate the perimeter of a circle using radius and diameter. Let’s begin.
