Question

The circumference of a circle is given by the formula C = 2 π r . Find r if the circumference is 352 meters and π is 227 .

Answer 1

The radius of the circle is 56 meters.

Explanation:

The circumference of a circle is given by the formula C = 2 π r

C = 352 and π = 22/7

Now plug in the given values in the above formula, we get

352 = 2* 22/7 * r

352 = 44/7 r

Now we have to simplify.

r = 352 * 7/44

r = 2464/44

r = 56 meters

The radius of the circle is 56 meters.

Hope this will helpful.
