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

SOLUTION

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

$\begin{gathered} Volume=\pi\times0.65^2\times7.5 \\ Volume=\pi\times0.4225\times7.5 \\ Volume=\pi\times3.16875 \\ Volume=9.954921721 \\ Volume\approx10.0m^3\text{ to the nearest tenth} \end{gathered}$

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