To find the volume of a cone, you can use the formula V = (1/3)πr^2h, where r is the radius and h is the height.

In this case, the diameter is given as 4 meters, so the radius would be half of that, which is 2 meters.

Using the formula, the volume would be:
V = (1/3) * 3.14 * 2^2 * 6
V = (1/3) * 3.14 * 4 * 6
V = (1/3) * 3.14 * 24
V = (3.14 * 24)/3
V = 75.36 cubic meters

Therefore, 75.36 cubic meters of sand is needed to fill the mold.
