Question

What is the surface area of a sphere if the radius is $14cm$?

• A. $1024c{m}^2$
• B. $6032c{m}^2$
• C. $2484c{m}^2$
• D. $2464c{m}^2$

Answer 1

The correct option is D $2464c{m}^2$

given:-

radius$=14cm$

surface area$=4\pi r^2$

$=88\times 28$

$=2464c{m}^2$

Hence,

the surface area of sphere is $2464c{m}^2$
