A cylindrical water tank has a radius of 4 meters and a height of 10 meters.
To find out how much water the tank can hold, calculate its volume using the formula for the volume of a cylinder:
$$ V = ext{base area} imes ext{height} = ext{(area of circle)} imes ext{height} = ext{(πr²)} imes h $$
What is the volume of the water tank in cubic meters?
