A pile of coal is stored in a barrel-shaped bin whose base has a radius of 3 meters. The height of the pile measures 1.5 meters. What volume of coal is in the pile (to the nearest hundredth)?
Area of circle = πr^2
πr^2*h = Volume
Insert values and calculate.
42.39
To find the volume of coal in the pile, we can use the formula for the volume of a cylinder.
The formula for the volume of a cylinder is V = πr^2h, where V is the volume, r is the radius of the base, and h is the height.
In this case, the radius is given to be 3 meters and the height is 1.5 meters. Plugging these values into the formula, we have:
V = π(3^2)(1.5)
V = π(9)(1.5)
V ≈ 42.39 meters^3
Therefore, the volume of coal in the pile is approximately 42.39 cubic meters.
