Volume of a Cylindrical Water Tank

A cylindrical water tank has a radius of 4 feet and a height of 10 feet. The tank is filled to a height of 6 feet with water. What is the volume of water in the tank, rounded to the nearest cubic foot? Use the formula for the volume of a cylinder: $$V = \pi r^2 h$$ where $r$ is the radius and $h$ is the height.
