Question

3. The diameter of the base of a cylinder is 0.4 m and
3
its height is
of its base radius. Find the volume
4
of the cylinder, giving your answer in litres.​

Answer 1

Answer:

Diameter of the cylinder = 0.4 m => radius (r) = 0.2 meter

Height of the cylinder (h) = 0.2x3/4 = 0.15 meter

Volume of the cylinder = πr2h

= 3.14 x (0.2)2 x 0.15

= 0.01884 cube meter

1 cube meter = 1000 litres

Volume of the cylinder in litres = 0.01884x 1000 = 18.84 litres
