A sandcastle mold is in the shape of a cone, with a diameter of 4 meters and a height of 6 meters. What volume of sand is needed to fill the mold? Use 3.14 for π
.
The volume of a cone can be calculated using the formula V = 1/3 * π * r^2 * h, where r is the radius and h is the height.
Given that the diameter of the cone is 4 meters, the radius is half of the diameter, which is 2 meters.
Plugging in the values:
V = 1/3 * 3.14 * (2^2) * 6
V = 1/3 * 3.14 * 4 * 6
V = 1/3 * 3.14 * 24
V = 25.12 cubic meters
Therefore, 25.12 cubic meters of sand is needed to fill the mold.
