Question

A conical pit having top diameter 3.5m is 12m deep. what is its capacity in liters?

Answer 1

Diameter,d = 3.5 m
Radius,r = 3.5/2 = 1.4
height,h = 12 m
Capacity = 1/3 Πr²h
= 1/3×22/7×1.4×1.4×12
= 1/3×22/7×14/10×14/10×12
= 24.64 m³
= 24.64×1000=24640 litres

Answer 2

24640 liters .........
