Diameter of top = 3.5 m
Radius = 3.5 / 2 m
Height = 12 m
Capacity = 1/3 pi r^2 h
= 22*3.5*3.5 * 12 / 7 * 3 * 2* 2
= 22*3.5 * 0.5
= 11 * 3.5
= 38.5 m^3
= 38.5 kilolitres [ 1 m^3 = 1 kilolitre]
Radius = 3.5 / 2 m
Height = 12 m
Capacity = 1/3 pi r^2 h
= 22*3.5*3.5 * 12 / 7 * 3 * 2* 2
= 22*3.5 * 0.5
= 11 * 3.5
= 38.5 m^3
= 38.5 kilolitres [ 1 m^3 = 1 kilolitre]
