Question

A conical pit diameter 3.5 m is 12 m deep. What is its capacity in kilolitres ?

Answer 1

Radius of pit = r= $\frac{3.5}{2}=1.75m$

height of pit = depth of pit = 12m
so, volume of pit = $\frac{1}{3}\pi r^{2}h=\frac{1}{3}\pi \times {1.75}^2\times 12=38.5m^3$

capacity of pit = 38.5 x 1 = 38.5 kiloltr
