Answer
$V\approx118\text{m}^3$
Work Step by Step
To find the volume of a cylinder, we simply use the formula $V=\pi r^2h$, where $r$ is the radius of the cylinder and $h$ is the height. We plug in the values for radius and height, as seen in the figure (The diameter in the figure is 5m. Since the radius is half the diameter, the radius is 2.5 m): $$V=\pi(2.5)^2(6)$$We simplify the exponent: $$V=(6.25)(6)\pi$$We multiply: $$V\approx118\text{m}^3$$
