Question

what would be the best formula to model the volume of the teepee shown? a volume of a cone b volume of a cylinder c volume of a triangular prism

Explanation:

A teepee's shape resembles a cone, with a circular base (or approximate circular base) and a pointed top, so the volume of a cone formula is the best fit. A cylinder has straight sides, and a triangular prism has a triangular base and rectangular sides, which don't match the teepee's shape.

Answer:
