A cylindrical water tank has a radius of 3 meters and a height of 5 meters. To find out the amount of water it can hold, we need to calculate the volume of the cylinder using the formula:
$$ V = ext{Base Area} imes ext{Height} $$
where the base area can be found by:
$$ ext{Base Area} = ext{Radius}^2 imes ext{π} $$
What is the volume of the tank, in cubic meters, rounded to the nearest whole number?
