Question

Determine the volume of a cylinder that is 7.5 meters high and whose bases have a radius of 0.65 meters. Calculate the volume using pie from your calculator and rounding to the nearest tenth

Answer 1

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the given parameters

`\begin{gathered} height=7.5m \\ radius=0.65m \end{gathered}`

STEP 2: Write the formula for finding the volume of a cylinder

`Volume=\pi r^2h`

STEP 3: Calculate the volume by substituting the values

`\begin{gathered} Volume=\pi*0.65^2*7.5 \\ Volume=\pi*0.4225*7.5 \\ Volume=\pi*3.16875 \\ Volume=9.954921721 \\ Volume\approx10.0m^3\text{ to the nearest tenth} \end{gathered}`

Hence, the volume of the given cylinder is approximately 10.0m³
