Question

A cylindrical tank is half full of oil. The cylinder has a base radius of 100cm. The height of the cylinder is 250cm. 1litre=1000cm How many litres of oil are in the tank

Answer 1

≈ 3927 litres

the volume (V) of a cylinder is calculated using the formula

V = πr²h ( r is the radius of base and h is the height )

V= π × 100² × 250 = 7853981.634 cm³

`(1)/(2)` V = 3926990.817 =
`(3926990.817)/(1000)` ≈ 3927 litres
