Question

find the surface area of sphere of radius is 7 cm

Answer 1

$surface \: area \: = 4\pi {r}^{2} \\ here \: r = 7cm \\ sa = 4\pi {(7cm)}^{2} \\ = 615.75 {(cm)}^{2}$
hope it helps

Answer 2

Ahola BrainLics !!
________________★

Surface Area Of a sphere = 4 πr^2


Given :

radius = 7 cm


so,

S.A = 4 *22/7*7*7

S.A = 614 cm^2
