Question

if surface area of a sphere is 676πcm².find its radius

Answer 1

4pier^2=676pie
r^2=676/4
r^2=169
r=13cm.

YOUR ANSWER IS 13CM

Answer 2

Hey mate..!!


Here's your answer..

_____________________________

$area \: of \: sphere = 4\pi {r }^{2} \\ so \: 4\pi \: {r}^{2} = 676\pi \\ 4 {r}^{2} = 676 \\ {r}^{2} = 169 \\ so \: r = 13cm$
Thus...Radius will be 13cm..
