Question

Find the volume of a sphere whose radius is 7 cm
$[Assume\pi =\frac{22}{7}]$

• A. $1437.33c{m}^3$
• B. $1500c{m}^3$
• C. $1600.33c{m}^3$
• D. $1750.33c{m}^3$

Answer 1

The correct option is A

$1437.33c{m}^3$

Radius of the sphere = 7 cm
Volume of the sphere $=\frac{4}{3}\pi r^3$
$=[\frac{4}{3}\times \frac{22}{7}\times (7{)}^3]c{m}^3$
$=\left(\frac{4312}{3}\right)c{m}^2$
$=1437.333c{m}^3$
Therefore, the volume of the sphere is $1437.33c{m}^3$.
