Question

$\text{The volume of a sphere of radius 10.5 cm is}\left(a\right)9702c{m}^3\left(b\right)4851c{m}^3\left(c\right)19404c{m}^3\left(d\right)14553c{m}^3$

Answer 1

Solution:-
Volume of sphere = $\frac{4}{3}\pi r^3$
= $\frac{4}{3}\times \pi \times 10.5\times 10.5\times 10.5$
Volume of metallic sphere = 4851 cm³
