Question

What's the volume of the cone​

Answer 1

Given:-

`\bullet` Radius (r) of the cone is 3 ft.

`\bullet` Height (h) of the cone is 9 ft.

To Find:-

The volume of the cone.

Solution:-

We know,

Formula of Volume of cone is
`(1)/(3)`πr²h

So, Volume of the cone =
`(1)/(3)` ×
`(22)/(7)` × (3)² × 9

Volume of the cone =
`(1)/(3)` ×
`(22)/(7)` × 3 × 3 × 9

Volume of the cone =
`(22 \: × \: 3 \: × \: 3 \: × \: 9)/(3 \: × \: 7)`

Volume of the cone =
`(1782)/(21)`

Volume of the cone = 84.86 cubic ft.

The volume of the cone is 84.86 cubic ft. [Answer]
