Question

A can with a dimeter of 8 in and height of 5 in what is the volume of the can

Answer 1

if it has a diameter of 8, that means its radius is half that, or 4.

`\textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=4\\ h=5 \end{cases}\implies V=\pi (4)^2(5)\implies V\approx 251.33~in^3`

Answer 2

The volume is the area of the ground plane times the height.

The area is πr², and r is half the diameter = 4.

So area = 3.14 x 4² = 50.24 and volume = 5 x 50.24 = 251.2

Therefore, the volume of the can is 251.2 inches²
