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.
