Question

Find the diameter of a sphere whose volume is4851 cu cm.

Answer 1

Volume of sphere=4/3πr^3
$4851 = \frac{4}{3} \pi {r}^{3}$
$\frac{4}{3} \times \frac{22}{7} {r}^{3} = 4851 \\ {r}^{3} = \frac{4851 \times 7 \times 3}{4 \times 22} \\ r = \sqrt[ =3]{1158.628} \\ r =10.5$
D=R*2
=10.5*2
=21cm.
