Answer:
Step-by-step explanation:
Surface area= 4 pie r^2
616 = 4×22/7 × r^2
616 ×7 / 4 × 22 = r^2
2191/44 =r^2
49.8 =r^2
7.06 =r

we know that
Area of a sphere=πr square = 616 cm square
= 22/7 × r square= 616 cm sq
= r square= 616 × 7/22
= r square = 196
= r = ✓196
= r = 14
So, Diameter of a sphere = 14 × 2
= 28
