HELPPP PLSSS!!!!!!!!!!! Find the volume of the cone.

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

Final answer:

To find the volume of a cone, you need to know the radius of the base and the height of the cone. The formula to calculate the volume of a cone is V = (1/3)πr²h.

Step-by-step explanation:

To find the volume of a cone, you need to know the radius of the base and the height of the cone. The formula to calculate the volume of a cone is V = (1/3)πr²h, where V is the volume, r is the radius of the base, and h is the height of the cone.

For example, let's say the radius of the cone's base is 3 cm and the height is 8 cm. Plugging these values into the formula, we get V = (1/3)π(3 cm)²(8 cm) = 24π cm³ ≈ 75.4 cm³ (rounded to the nearest hundredth).

Answer:

The volume of cone is
\boxed{\tt{167.47}} unit³.

Step-by-step explanation:

Solution :

As per given question we have provided :

  • ➝ Radius of cone = 4 units
  • ➝ Height of cone = 10 units

Here's the required formula to find the volume of cone :


{\longrightarrow{\pmb{\sf{V_((Cone)) = (1)/(3)\pi{r}^(2)h}}}}

  • V = Volume
  • π = 3.14
  • r = radius
  • h = height

Substituting all the given values in the formula to find the volume of cone :


{\longrightarrow{\sf{Volume_((Cone)) = (1)/(3)\pi{r}^(2)h}}}


{\longrightarrow{\sf{Volume_((Cone)) = (1)/(3) * 3.14{(4)}^(2)10}}}


{\longrightarrow{\sf{Volume_((Cone)) = (1)/(3) * 3.14{(4 * 4)}10}}}


{\longrightarrow{\sf{Volume_((Cone)) = (1)/(3) * 3.14{(16)}10}}}


{\longrightarrow{\sf{Volume_((Cone)) = (1)/(3) * 3.14 * 16 * 10}}}


{\longrightarrow{\sf{Volume_((Cone)) = (1)/(3) * 3.14 * 160}}}


{\longrightarrow{\sf{Volume_((Cone)) = (1* 3.14 * 160)/(3)}}}


{\longrightarrow{\sf{Volume_((Cone)) = (3.14 * 160)/(3)}}}


{\longrightarrow{\sf{Volume_((Cone)) = (502.4)/(3)}}}


{\longrightarrow{\sf{Volume_((Cone)) \approx 167.47}}}


\star{\underline{\boxed{\sf{\purple{Volume_((Cone)) \approx 167.47\: {unit}^(3)}}}}}

Hence, the volume of cone is 167.47 unit³.
