Identify the formula for the volume of a cylinder, which is given by:
\(V = \pi r^2 h\)
where \(V\) is the volume, \(r\) is the radius, and \(h\) is the height.
Substitute the given values for the radius and height into the formula. Here, the radius \(r = 2\) meters and the height \(h = 5\) meters, so the formula becomes:
\(V = \pi (2)^2 (5)\)
Calculate the square of the radius:
\((2)^2 = 4\)
Multiply the squared radius by the height:
\(4 \times 5 = 20\)
Multiply the result by \(\pi\) to find the volume:
\(V = 20 \pi\) cubic meters. To get the numerical value, multiply 20 by the approximate value of \(\pi \approx 3.1416\), then round your answer to the nearest tenth.
