Question

find the surface area of sphere who's volume of sphere is 523.33 cubic cm .(π= 3.14)​

Answer 1

Answer:

$volume \: of \: sphere = \frac{4}{3}\pi {r}^{3} \\ and \: volume \: of \: sphere =523.33 {cm}^{3} \\ therefore \: 523.33 = \frac{4}{3} \times 3.14 \times {r}^{3} \\ 523.33 = 4.19 {r}^{3} \\ {r}^{3} = \frac{523.33}{4.19} \\ r = \sqrt[3]{124.9} \\ r = 4.9 \: cm \\ surface \: area \: of \: the \: given \: sphere = 4\pi {r}^{2} \\ = 4 \times 3.14 \times 4.9 \\ = 61.544 {cm}^{2}$
