Question

Find the surface area of a sphere of diameter of 14​

Answer 1

Answer:

r=7

surface area of a sphere=4πr^2

=4×22/7×7×7

=616 cm^2

Answer 2

Step-by-step explanation:

Formula is ,

$4\pi {r}^{2}$

r = 7cm

SA =

$4 \times \frac{22}{7} \times 7 \times 7 \\ = 4 \times 22 \times 7 \\ = 616 \: {cm}^{2}$
