The volume of a cone can be calculated using the formula V = (1/3) * π * r^2 * h, where V is the volume, π is approximately 3.14159, r is the radius, and h is the height.
Since the diameter is given as 20 cm, the radius (r) is half of that, which is 10 cm.
Plugging in the values, we get:
V = (1/3) * 3.14159 * 10^2 * 15
V = (1/3) * 3.14159 * 100 * 15
V = 3.14159 * 100 * 5
V = 3141.59 cubic centimeters
Thus, the volume of the cone is approximately 3141.59 cubic centimeters.
The closest option from the given choices is 314 cubic centimeters.
