Question

find the diameter of a circle whose area is 314 M2​

Answer 1

Answer:

area = pie * r * r

314 *7/22 = r^2

2r = diameter

Answer 2

Answer:

                      are of circle=πr^2=314

                      314*7/22=r^2

                    r^2=99.09

r=√99.09=9.95

                diameter=2r= 19.9m
