Explanation:

Given :-

  • Height of cone :- 11 feet
  • Diameter of cone :- 14 feet , radius = 7 feet

To Find :-

  • Volume of cone

Solution:-

Formula for volume of cone = 1/3πr²h

  • putting the known values ,

Volume = 1/3×3.14×7²×11 cubic ft.

Volume = 564.15 cubic ft.

Answer:

  • 564.15 cubic ft


\:

Explanation:

In the question, it is given that a cone has a diameter of 14 feet and a height of 11 feet and we have to find the volume of the cone.


\:

To Find the volume of the cone, we must know this formula :


\\{\longrightarrow{ \qquad{\underline{\boxed {\pmb{\frak { Volume_((cone) )= (1)/(3) \: \pi {r}^(2)h }}}}}}} \\ \\

Where,

  • r refers to the radius of the cone. As the diameter is 14 ft, therefore the radius will 7 ft.

  • h refers to the height of the cone.

Now, we will substitute the values in the formula :


\\ {\longrightarrow{ \qquad{{ {\pmb{\sf { Volume_((cone) )= (1)/(3) * 3.14 * {(7)}^(2) * 11 }}}}}}} \\ \\


{\longrightarrow{ \qquad{{ {\pmb{\sf { Volume_((cone) )= (1)/(3) * 3.14 * 49 * 11 }}}}}}} \\ \\


{\longrightarrow{ \qquad{{ {\pmb{\sf { Volume_((cone) )= (1)/(3) * 3.14 * 539 }}}}}}} \\ \\


{\longrightarrow{ \qquad{{ {\pmb{\sf { Volume_((cone) )= (1)/(3) * 1692.46 }}}}}}} \\ \\


{\longrightarrow{ \qquad{{ {\pmb{\sf { Volume_((cone) )= (1692.46)/(3) }}}}}}} \\ \\


{\longrightarrow{ \qquad{{ {\pmb{\sf { Volume_((cone) )= \: \: \underline{ \boxed{ \frak{564.15 } }} }}}}}}} \: \: \bigstar \\ \\

Therefore,

  • The volume of the cone is 564.15 ft³ .
