Answer: 7cm

Explanation:

The surface area of a sphere is calculated by using the formula:

A = 4πr²

Since the surface area is 616cm², using the formula given, the radius will be calculated thus:

A = 4πr²

616 = 4 × 22/7 × r²

616 = 88/7 × r²

Multiply both side by 7/88

616 × 7/88 = 88/7 × 7/88 × r²

49 = r²

r = ✓49

r = 7

The radius is 7cm
