Question
Calculate the surface area of a sphere, given that its
volume is (792/7) cm3.Solution
Let radius of the sphere = ‘r’ cm Volume of the sphere = (4/3)πr3 = (4/3) × (22/7) × r3 = {(88/21) × r3} cm3 So, {(88/21) × r3} = (792/7) Or, r3 = 27 = 33 Or, r = 3 Now, Surface area of the sphere = 4πr2 = 4 × (22/7) × 32 = (792/7) cm2
