Question

A cylindrical drum is 20m tall and has the inner diameter of 30m. How many liters of water can be stored in it ?​

Answer 1

14137167 liters approximately

Explanation:

Total Volume of a cylinder

V = π R² H

where R - base radius

H = height

Given diameter of base = 30m, base radius R = 30/2 = 15

H = 20m

Volume = π x 15² x 20 = 4500π m³ = 14,137.16694 m³

Since 1 m³ = 1000 liters

this works out to 14137.16694 x 1000 ≈ 14137167 liters
