The formula for the volume of a cone is V = (1/3)πr^2h, where r is the radius and h is the height of the cone. Given the diameter of the cone is 2 cm, the radius (r) is half of the diameter, which is 1 cm.
Plugging the values into the formula:
V = (1/3) * 3.14 * (1^2) * 6 = 18.84 cubic centimeters.

Given the diameter of the cone is 4 meters, the radius (r) is half of the diameter, which is 2 meters.
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 of the cone.
Plugging the values into the formula:
V = (1/3) * 3.14 * (2^2) * 6 = 100.48 cubic meters.
