Question

A conical tent is $3m$ deep and the circular top has radius $1.75m,$ then find the capacity of the tank in litres.

Answer 1

Given:

Radius, $r=1.75m$

Height, $h=3m$

Volume of cone $=\frac{1}{3}{r}^{2}h$

$=\frac{1}{3}\times \frac{22}{7}\times {\left(1.75\right)}^2\times 3$

$=22\times 0.25\times 1.75$

$=9.625m^3$

Now,

$1m^3=1000\text{liters}$

$9.625m^3=9.625\times 1000\text{liters}$

$=9625\text{liters}$
