Question

The diameter of the top of a conical reservoir is 4.5 m and depth is 14 m.find the volume reservoir in litres.

Answer 1

hey there !!

the diameter of conical reservoir = 4.5m
therefore , it's radius = 4.5/2 = 2.25

and , depth of reservoir = 14 m
so , its height = 14m

now ,

volume of conical reservoir = 1/3πr²h

volume of reservoir = 1/3 × 22/7 × 2.25×2.25×14

volume of reservoir = 74.25m³

hence the volume of reservoir is 74.25m³

hope it helps !!
