Find the volume o

Answer :

Given: surface area of sphere = 154 cm2

And we know surface area of sphere is given by,


Surface area = 4πr2


Substituting values in the above equation, we get





r2 = 12.25


r = √12.25


r = 3.5


If radius of sphere is 3.5 cm, then volume can be easily found as the formula of volume of sphere is given by,


Volume = 4πr3/3


Volume =


Volume =


Volume = 179.67


Thus, volume of sphere is 179.67 cm3.
