Question

Find the surface area and the volume of a ball whose radius is 14 cm.

Answer 1

Given, r = 14 cm

Surface area of ball = 4πr²

= 4 × \(\frac { 22 }{ 7 }\) × 14 × 14

= 2464 cm²

Volume of the ball = \(\frac { 4 }{ 3 }\)πr³

= \(\frac { 4 }{ 3 }\) × \(\frac { 22 }{ 7 }\) × (14)³

= 40245.33 cm³
