Question

Find the volume of a cone. Round your answer to the nearest wholenumber.7 ft4 ft

Answer 1

117 cubic feet

Step-by-step explanation:

From the diagram:

• The radius of the cone, r = 4 ft

,

• The perpendicular height, h = 7 ft

`\text{Volume of a cone=}(1)/(3)\pi r^2h`

Substitute the given values:

`\begin{gathered} V=(1)/(3)*\pi*4^2*7 \\ =117.2ft^3 \\ \approx117\; ft^3 \end{gathered}`

The volume of a cone is 117 cubic feet (to the nearest whole number).
