Volume of Water in a Cylinder

A cylindrical tank has a radius of 3 meters and a height of 5 meters. The tank is filled with water to a height of 4 meters. What is the volume of water in the tank, in cubic meters?

Use the formula for the volume of a cylinder, which is given by:

$$ V = ext{Base Area} imes ext{Height} $$

where the Base Area is calculated as:

$$ ext{Base Area} = ext{Radius}^2 imes ext{π} $$
