Question

Find the volume of a sphere-shaped metallic shotput having a diameter of $8.4$ cm (Take $\pi =\frac{22}{7}$)

Answer 1

Diameter $=8.4$ cm
Therefore, radius $=4.2$ cm
Volume of the sphere $=\frac{4}{3}\pi r^3$
$=\frac{4}{3}\times \frac{22}{7}\times 4.2\times 4.2\times 4.2$

$=310.464$ cu.cm
