Question

how to find the radius of a circle when given the circumference

Answer 1

Hey user

Here is your answer =>

Let is understood by an example

If circumference of a circle is 154 m . Find its radius .

We know that ,

Circumference of circle = 2 × pi × r

》154 = 2 × 22/7 × r

》154 × 7/22 × 2 × r

》r = 7 × 7/2

》r = 49/2

》r = 24.5 m

So the radius is 24.5 m

That's how you can find the radius when the circumference of circle is given .

Thank you .
