Question

volume of a sphere is 38808 cm cube find its radius and hence its service area

Answer 1

$38808 = \frac{4}{3} \pi {r}^{3} \\ 38808 = \frac{4}{3} \times \frac{22}{7} \times {r}^{3} \\ \frac{38808 \times 21}{88} = {r}^{3} \\ r = 21$
radius of sphere is 21 cm
$4\pi {r}^{2} \\ 4 \times \frac{22}{7} \times 21 \times 21 \\ 5544 {cm}^{2}$
surface area of cube is 5544sq.cm
