Could someone please check my answer!

Suppose a cone and a pyramid both have a base area of 150 mm². If they have the same height, which would have a larger volume? Using complete sentences, justify your answer.
Ans: Given that a cone and a pyramid both have the same base area of 150 mm² and the same height, we need to determine which of these two shapes would have a larger volume.


The formula of a cone is given by:
V_cone = ⅓ π r² h
Where r is the radius of the base and h is the height. However, since the base area A, is provided, we can write this as:
A = πr²
Thus, the volume of the cone can be expressed in the terms of base area A and height as h: V_cone = ⅓ Ah


The formula for the volume of a pyramid is given by:
V_pyramid = ⅓ Bh
where B is the base area and h is the height. Given that the base area B is 150 mm², the volume of the pyramid is:
V_pyramid = ⅓ Bh = ⅓ × 150 × h


Since both the cone and pyramid have the same base area and height, their volumes can be directly compared:
V_cone = ⅓ × 150 × h
V_pyramid = ⅓ × 150 × h


Thus, the volume of the cone is equal to the volume of the pyramid when both have the same base area and height. Therefore, neither shape has a larger volume, they both have equal volumes.
