Question

Find the surface area of a sphere of radius $14$ cm.

• A. $2464{cm}^2$
• B. $1446c{m}^2$
• C. $2446c{m}^2$
• D. $2664c{m}^2$

Answer 1

The correct option is A $2464{cm}^2$

We know that the surface area of sphere with radius $r$ is $A=4\pi r^2$.

It is given that the radius of the sphere is $14cm$.

Then, $A=4\pi r^2=4\times \frac{22}{7}\times (14{)}^2=4\times \frac{22}{7}\times 196=2464$$c{m}^2$.

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

Therefore, option $A$ is correct.
