Step-by-step explanation:
Given:
surface area = 616 cm
to find: volume of sphere
therefor
surface area of sphere = 616
4πr^2 = 616
22/7 X r^2 = 616/4
r^2 = 616 X 7/ 4 X 22
r^2 = 49
r = √49
r = 7
(important do remember to cancel where needed)
now,
volume of sphere = 4/3πr^3
volume of sphere = 4/3 X 22/7 (7)^3
volume of sphere = 88/21 X 343
volume of sphere = 30184/21
volume of sphere = 1436.76 ans
