Question

Find perimeter of a circle frm whch a circle has been cutt off?

Answer 1

Answer:

To find the perimeter, you actually need to find the circumference of a circle.

Step-by-step explanation:

The formula to find the circumference is:

C= 2 pi times r

The r is the radius of the circle. The 2 stays the same. If you have the radius then you are fine.

E.g. If you have a circle and you're given that the radius the distance from the center to a point on the circle is 10. Since you have the radius, all you will have to do is C= 2 pi times (10). So 2 times 10 is 20 so it'll be 20 pi for the circumference.

I hope this helped sorry if it's confusing. If you have any questions please ask.
