Volume of Water in a Cylindrical Tank

A cylindrical water tank has a radius of 4 feet and a height of 10 feet. The tank is filled to a depth of 5 feet with water. To find out how much water is in the tank, which is equivalent to calculating the volume of the portion filled with water, you will use the formula for the volume of a cylinder:

$$ V = ext{base area} imes ext{height} $$

where the base area $$ A $$ of the cylinder can be expressed as:

$$ A = ext{radius}^2 imes ext{π} $$

Calculate the volume of water currently in the tank.
