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
