Question

This surface area of a sphere is 144 cm square then its volume is

Answer 1

Step-by-step explanation:

Surface area of a sphere=4πr^2

given surface area is 144cm square

144=4πr^2

r^2=144/4π

r^2=11.45

r=3.383

Now

volume of sphere=(4/3)πr^3

volume= (4/3)×π×(3.383)^3

volume=162.18 cm cube
