Question

A cylindrical barrel has a radius of 1.2 feet and a height of 4 feet. Find the volume of the barrel.

Answer 1

18.1 ft³

Explanation:

Given:

Radius (r) = 1.2 ft

Height (h) = 4 ft

We can determine the volume of the cylindrical barrel using the following formula:

`V=\pi\cdot r^2\cdot h`

We substitute each value and calculate the volume, like this:

`\begin{gathered} V=\left(3.14\right)\left(1.2^2\right)\left(4\right) \\ \\ V=18.1\text{ ft}^3 \end{gathered}`

The volume of the barrel is 18.1 ft³
