Question

a conical pit of top diameter 3.5 M is 12 m deep. what is its capacity in litre?

Answer 1

$volume \: of \: cone=\pi \times {r}^{2} \times \frac{h}{3} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{22}{7} \times (\frac{3.5}{2} )^{2} \times \frac{12}{3} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{22}{7}\times \frac{12.25}{4} \times 4$
4 gets cancelled.
$= \frac{22\times 12.25}{7} = \frac{269.5}{7} = 38.5 {m}^{3}$
