A sandcastle mold is in the shape of a cone with a Demeter of 4 meters and a height of 6 m what volume of sand is needed to fill the mold use 3.14 for pi
The formula for the volume of a cone is V = (1/3) * π * r^2 * h, where V is the volume, π is approximately 3.14, r is the radius of the base, and h is the height of the cone. Given that the diameter of the cone is 4 m, the radius (r) would be half of that, which is 2 m.
Plugging in the values, we get:
V = (1/3) * 3.14 * (2^2) * 6
V = (1/3) * 3.14 * 4 * 6
V = (1/3) * 3.14 * 24
V = 3.14 * 8
V = 25.12
Therefore, approximately 25.12 cubic meters of sand is needed to fill the mold.
