First, we need to find the radius of the cone. The radius is half of the diameter, so in this case, the radius is 10 cm.
Next, we can calculate the volume of the cone using the formula: V = (1/3) * pi * r^2 * h
V = (1/3) * 3.14 * 10^2 * 15
V = (1/3) * 3.14 * 100 * 15
V = (1/3) * 3.14 * 1500
V = (1/3) * 4710
V = 1570 cm^3
Therefore, the volume of the cone with a diameter of 20 cm and a height of 15 cm is 1570 cm^3.
