what is the volume of a cone with the height being 18 centimeters and diameter being 25.4

The radius of the cone is half of the diameter, so the radius is 25.4/2 = 12.7 cm.

The formula for the volume of a cone is V = (1/3) * π * r^2 * h, where r is the radius and h is the height.

Substitute the values into the formula:

V = (1/3) * π * (12.7)^2 * 18
V = (1/3) * π * 161.29 * 18
V = (1/3) * π * 2903.22
V ≈ 3050.41 cubic centimeters

So, the volume of the cone is approximately 3050.41 cubic centimeters.
