Question

A reservior in the shape of a right circular cylinder is to contain 79200 l of water if the radius of cylinder is 3m find its height​

Answer 1

Answer:

Radius of cylindrical reservoir = 3m

let it's height be h.

Volume of reservoir = volume of water

pie×r^2×h = 79200 litres or 79.2 m^3

22/7 × 3×3 × h = 79.2 m^3

h = (79.2 ×7) / 22×9

h = 554.4 / 198

h = 2.8 m
