Question

The CSA of sphere is 616m^2 . Then find its radius

Answer 1

hope it will help u
so radius =7m

Answer 2

HEYA!!

Given,

CSA of sphere = 616m^2

CSA of sphere = $4\pi {r}^{2}$

$\pi {r}^{2} = \frac{616}{4}$

$\pi {r}^{2} = 154 \\ \frac{22}{7} \times {r}^{2} = 154 \\ {r}^{2} = 154 \times \frac{7}{22} \\ {r}^{2} = 49 \\ r = \sqrt{49} \\ r = 7m$
