Question

Find the volume of the cone.

Either enter an exact answer in terms of or use 3.14 for TT and round your final answer to the nearest hundredth.
units
4 and 3

Answer 1

We know,

`{ \longrightarrow \bf \qquad { { Volume_((cone) )= (1)/(3) \pi {r}^(2)h }}}`

Where,

• r is the base radius of the cone.
• h is the height of thr cone.

Here,

• Radius of the cone is 3 .
• Height of the cone is 4 .

⠀

Substituting the value in the formula :

We will take the value of π as 3.14 .

⠀

`{ \longrightarrow \sf \qquad { { Volume_((cone) )= (1)/(3) * 3.14 * {3}^(2) * 4 }}}`

⠀

`{ \longrightarrow \sf \qquad { { Volume_((cone) )= \frac{1} {\cancel{3}} * 3.14 * \cancel9 * 4 }}}`

⠀

`{ \longrightarrow \sf \qquad { { Volume_((cone) )= {1} * 3.14 * {3} * 4 }}}`

⠀

`{ \longrightarrow \sf \qquad { { Volume_((cone) )= {1} * 3.14 * 12 }}}`

⠀

`{ \longrightarrow \bf \qquad { { Volume_((cone) )= 37.68 }}}`

⠀

Therefore,

• The volume of the cone is 37.68 units³.
