PLEASE HELP ME!!! I'M BAD AT GEOMETRY!!!
7nadin3 [17]

Answer:

Manuel would be correct, the volumes would be equal.

Step-by-step explanation:

The formulae for finding the volume of pyramids and cones both include dividing three (multiplying by \frac{1}{3}).

Square pyramid formula: \frac{1}{3}×B×h where B is the area of the base. By plugging in numbers we have that B=314.159 and h=5. 314.159×\frac{1}{3}×5=523.5983.

Cone formula: The basic formula is the same: \frac{1}{3}×B×h, but the area of the base is found using the circle formula of π×r². For the cone we have B=314.159 and h=5. 314.159×\frac{1}{3}×5=523.5983.

Since both of these formulas came up with the same answer, we can conclude that Cone W has the same volume as Pyramid X, which is Manuel's answer.
