Question

A conical pit of top diameter 3.5 m is 12 m deep. What is its capacity in kiloliters?

Answer 1

Radius of the conical pit, r = $\frac{3.5}{2}$ m = 1.75 m
Depth of the conical pit, h = 12m

Volume of conical pit = $\frac{1}{3}\pi$r²h
= $\frac{1}{3}$ × $\frac{22}{7}$ × 1.75 m × 1.75 m × 12 m
= 38.5 m³
= 38.5 × 1 kiloliter's
= 38.5 kl
∴ Capacity of the conical pit is 38.5 kiloliters.
