A cylindrical tank has a radius of 4 meters and a height of 10 meters. The tank is filled with water to a height of 6 meters. What is the volume of the water in the tank?
To find the volume of a cylinder, you can use the formula:
$$ V = ext{base area} imes ext{height} $$
where the base area for a cylinder is calculated by:
$$ ext{base area} = ext{π}r^2 $$
