Question

Find the capacity in kilolitres of a cylindrical rainwater tank of height 3m and diameter 4m.

Answer 1

The capacity of cylindrical rainwater tank is
`37.68 m^3`

Explanation:

Height of cylindrical tank = 3 m

Diameter of cylindrical tank = 4 m

Radius of cylindrical tank =
`(diameter)/(2) = (4)/(2) = 2 m`

Volume of cylinder =
`\pi r^2 h`

Volume of cylinder tank=
`3.14 * (2)^2 (3)`

Volume of cylinder tank=
`37.68 m^3`

`1 m^3` =1 kilolitres

So,
`37.68 m^3` = 37.68 kilolitres

Hence The capacity of cylindrical rainwater tank is
`37.68 m^3`
