Question

Find the volume of the coneheight 12 ftbase diameter 8ftuse the value 3.14 for pie

Answer 1

Given Parameters

height 12 ft

base diameter 8ft Therefore, the radius r =4ft

use the value 3.14 for pie

The formula

$\begin{gathered} \text{The volume of a cone =}\frac{1}{3}\pi r^2h \\ \\ \text{Substitute the given parameters into the formula} \\ \\ \text{The volume of a cone =}\frac{1}{3}\times3.14\times4^2\times12 \\ \\ \text{The volume of a cone =}\frac{1}{3}\times3.14\times16^{}\times12 \\ \text{The volume of a cone =}3.14\times16^{}\times4 \\ \text{The volume of a cone =}3.14\times64 \\ \\ \text{The volume of a cone =200.96 ft}^3 \end{gathered}$

The final answer

$\text{The volume of a cone =200.96 ft}^3$
