So the formula for circumference is 2πr = 136 m where r = radius
Let the radius be r
so 2 x 22/7 x r = 136
r = 136/2 x 7/22
r =  21.63 m

so area = 2πr² = 2 x 22/7 x (21.63)² = 2941.68 m²

2) so area = 2πr² = 2 x 22/7 x (21.63)² = 2941.68 m²

3) so area = 2πr² = 2 x 22/7 x r² = 308 m²

r² = 308/44 x 7

r² = 49

so r = 7 m

so diameter = 2 x 7 = 14 m
hope it helps
plz mark as best
