$\huge\boxed {answer}$

Given Radius = 14 cm

therefore ,

Surface area =

$4\:π\:r² \\ 4\:×\:\frac{22}{7}\:×\:14² \\ 4\:×\:\frac{22}{7}\:×\:14\:×\:14 \\ 2464\:cm²$

here is your answer ☝

Answer 2

Solution:

Radius of sphere = 14cm

Surface area of sphere = 4πr²

=> 4πr²

=> 4×22/7×14×14 ( π = 22/7 )

=> 2464cm²

Hence, surface area of sphere is 2464cm².
