If the surface ar

Answer :

Surface area of sphere = 2826 cm2

Surface area of sphere is given by,


Surface area = 4πr2


Substituting the values in above equation,


2826 = 4 × 3.14 × r2



r2 = 225


r = √225


r = 15


Volume of sphere is given by,


Volume =


Volume =


Volume = 14130


Thus, volume of sphere is 14130 cm2.
