10-146.

From problem 10-143, you learned that the volume of a coneis one-third the volume of a cylinder.

The equation for the volume of a cylinder is:
Volume = (area of base) (height)
So the volume of a cone is:

The base is a circle with a radius of 6 inches. So using the equation for area of a circle:
Area of base = (6²)π= 36π

The height of the cylinder is 8 inches. Substitute the known values into the volume equation for a cone:

Now simplify to get the answer.
