Answer:
according to question :-
area = 616
πr^2 = 616
22/7 * r^2 = 616
r^2 = 616 * 7/ 22 = 196
r^2 = 196
r = √196 = 14
r = 14
now
circumference = 2πr = 2*22*7 * 14 = 2*22*2 = 88
circumference = 88 cm
hope you understand plz thank my answer

Answer:
pie r ² = 616 cm²
r² = 616 / 3.1416
r² = 196
r = 14 cm
Than,
circumference of circle = 2pie r
2 * 3.1416 * 14 cm
