Question

The largest sphere is curved out of cube of side $14cm$. Find surface area of sphere.

Answer 1

We have,

Edge of cube $=$ Diameter of the sphere $=14cm.$

Then, radius of sphere$=7cm.$

Since, Surface area of sphere$=4\pi r^2$

$=4\times \frac{22}{7}\times 7^2$

$=88\times 7$

$=616c{m}^2$

Hence, this is the answer.
