Question

Find the volume of the cylinder. Round your answer to the nearest hundredth.

Answer 1

notice the picture above, the "diameter" is 4.3, meaning its radius is half that, or 2.15, and it has a height of 4.7.


`\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h\qquad \begin{cases} r=2.15\\ h=4.7 \end{cases}\implies V=\pi (2.15^2)(4.7)\\\\\\ V=21.72575\pi`

Answer 2

The volume of the cylinder is 68.25 cubic feet.

Explanation:

To find the volume of a cylinder, first we have to take a look of the equation to calculate it:

`CylinderVolume=π*r^(2)*h`

Where π is the pi number (3.1415), r is the radius (4.3/2=2.15 ft) and h is height (4.7 ft).

Replacing it in the equation we have:

`CylinderVolume=3.1415*(2.15)^(2)*(4.7)=68.25`

The volume of the cylinder is 68.25 cubic feet.
