Question

Find the volume of this cone.Use 3 for TT.14 ft14 ftV = Tr?h=3V ~ [?]ft

Answer 1

Given the image find the volume of this cone:

The volume of this cone =

`\begin{gathered} V=(\pi r^2h)/(3) \\ where\pi\text{ = 3} \\ d=14 \\ r=(d)/(2)=(14)/(2)=7ft \\ h=4ft \end{gathered}`

radius = 7ft

height = 4ft

Volume of the cone =

`\begin{gathered} V=(3(7)^2(4))/(3) \\ V=49(4) \\ V=196ft^3 \end{gathered}`

Therefore the volume of the cone = 196ft³
