Question

Volume of water that can be stored in a spherical tank of diameter $42cm$ is.

[ use $\pi =\frac{22}{7}$ ]

• A. $38,808c{m}^3$
• B. $39,808c{m}^3$
• C. $28,808c{m}^3$
• D. $31,808c{m}^3$

Answer 1

The correct option is A $38,808c{m}^3$

We know that,
Volume of sphere is $\frac{4}{3}\pi r^3$.

Given that,
Diameter of sphere is $42cm$.

Now,
Volume of tank
$=\frac{4}{3}\times \frac{22}{7}\times {21}^3$
$=38,808c{m}^3$
