If a solid sphere of radius 10 cms is moulded into 8 spherical solid balls of equal radius, then surface area of each ball (in sq.cm) is ?  Choose the correct answer:
A) 100 π B) 101/π C) 99 π/12 D) 54/13π E) 22/10π
Explanation:   4/3 π x 10 x 10 x 10 = 8 x 4/3 π rxrxr   r = 5   4π x 5 x 5 = 100π   100 πNSWER IS 100 π
