Question

Find the surface area area of a sphere of radius 14 cm (takeπ=22/7)

Answer 1

area of circle = 4πr²

therefore, 4 * 22/7 * 14²

=4 * 22/7 * 196

=4 * 616

=2464

Answer = The Area will be 2464cm²

Answer 2

Step-by-step explanation:

Radius of a sphere is 14 cm.

Surface area of a sphere = 4π(r) ^2 sq. unit

$= 4\pi {r}^{2} \: \: \: \: sq.unit$

$= 4 \times \frac{22}{7} \times 14 \times 14 \: \: \: \: {cm}^{2}$

$= 4 \times 22 \times 14 \times 2 \: \: \: {cm}^{2}$

$= 2464 \: \: \: \: {cm}^{2}$

The surface area of a sphere is 2464 sq. c.m
