Question

If the circumference of a circular sheet is 154m,find its radius.

Answer 1

circumference of circular sheet =2πr=154m
                                                =2*22/7*r=154
                                                ⇒r=154*7/22*1/2=24.5m
Therefore radius of the circular sheet r=24.5m

Answer 2

Circumference = 2πr
154 = 2 × 22 × r
               7
77 × 7  = r 
   22

24.5 = r
