Let the radius of the circle be 'r'm
Given circumference=2πr=616m
πr=308m
r=308(7/22)
r=14×7m
r=98m
Area=πr²=(22/7)(98)(98)=30184m²

the circumference=616m
2πr=616 (where r=radius)
πr=308
r=98
then,the area=πr²
=22/7×98×98
=22×14×98
= 30184m
2πr=616 (where r=radius)
πr=308
r=98
then,the area=πr²
=22/7×98×98
=22×14×98
= 30184m
