Given,
πr 2 =616
r 2 = 22/616×7
r 2=28×7
r=14
Therefore, Circumference = 2πr=2×7/22×14=88 cm

Answer:
616 = πr^2
616 = πr^2616x 7 = r^2
616 = πr^2616x 7 = r^2÷ 22
616 = πr^2616x 7 = r^2÷ 22r^2 = 196
616 = πr^2616x 7 = r^2÷ 22r^2 = 196 r = 14
616 = πr^2616x 7 = r^2÷ 22r^2 = 196 r = 14 circumference = 2πr .
616 = πr^2616x 7 = r^2÷ 22r^2 = 196 r = 14 circumference = 2πr .= 2 x 22/7 x 14
616 = πr^2616x 7 = r^2÷ 22r^2 = 196 r = 14 circumference = 2πr .= 2 x 22/7 x 14= 88 cm.
