Answer 2

Answer:

Radius=7m

Step-by-step explanation:

given, area of the circle=154m^2

area of a circle =πr^2

so, substituting values,

                          22/7 * r^2=154m^2

                           r^2=154 * 7/22

                           r^2=49

                           r=root of 49

   which is 7

                           so , r=7m
