Question

The circumference of the base of a cylindrical tank is 88m and it is 15m deep. Find how much litres

of water can be filled in the tank?

Answer 1

Volume of Cylinder = πr²h

Where r = radius, h = height.

Circumference of the base = 88

That is 2πr = 88
πr = 88/2
πr = 44
r = 44/π h = 15 m

Volume = πr²h = π *(44/π)*(44/π)* 15

Volume = (44*44*15) / π = 9243.719 m³

But 1 m³ = 1000 litres

Therefore Volume in litres = 9243.719 * 1000 = 9243719 litres

Volume ≈ 9243719 litres
