Find the radius of the circle having circumference as 50cm and express your answer in form of pie

A: 50/π

B: 25

C: 50/2π

D: 26

Correct Answer : C

Given circumference to be 50cm , let the radius be r , we substitute the values in the formula
Circumference = 2πr

50 = 2 × π × r

50 = 2πr

We divide both sides by 2π to find the radius(r)

r = 50/2π

Therefore radius=25/π
