Answer 1

Surface area of sphere is =616 cm^2
$4\pi( {r}^{2} )$
$4( \frac{22}{7} )(r \times r) = 616 \\ \frac{22}{7} {r}^{2} = \frac{616}{4} \\ {r}^{2} = \frac{154 \times 7}{22} \\ {r}^{2} = 7 \times 7 \\ r = 7 \: cm$
volume of sphere
$(\frac{4}{3} )( \frac{22}{7} )( {r}^{3} ) \\ \frac{4}{3} \times \frac{22}{7} \times (7 \times 7 \times 7) \\ \frac{4}{3} \times 22 \times 7 \times 7 \\ \frac{4312}{3} {cm}^{3}$
