Question

If h = 7 units and r = 3 units, then what is the volume of the cone shown above?

Answer 1

Question:-

If h = 7 units and r = 3 units, then what is the volume of the cone shown above ?

Answer:-

Given:-

`\bullet` Height (h) of the cone is 7 units.

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

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 × 7

=
`(1)/(3)` ×
`(22)/(7)` × 9 × 7

=
`(22 \: × \: 9 \: × \: 7)/(3 \: × \: 7)`

=
`(1386)/(21)`

= 66 cubic units.

The volume of the cone is 66 cubic units. [Answer]

Answer 2

Explanation:

h = 7 units

r = 3 units

Volume of cone = (1/3) *πr²h

`= (1)/(3)* (22)/(7)*3*3*7\\\\= 22 *3\\\\= 66 cubic units`
