Question

Find the volume of the cone using 3 as pi

Answer 1

Given:

The height of the cone, h=8 in.

The diameter of the base of the cone, D=3 in.

The radius of the cone is,

`r=(D)/(2)=(3)/(2)=1.5\text{ in}`

The volume of the cone can be calculated as,

`\begin{gathered} V=(1)/(3)\pi r^2h \\ =(1)/(3)*3*1.5^2*8 \\ =18in^3 \end{gathered}`

Therefore, the volume of the cone is 18 in^3.
