The volume formulas for cylinders, cones, and spheres all include:
- pi (3.14) (it is often represented as π in formulas)
- radius (it is a key component in calculating the volume of these shapes)
The terms "hypotenuse" and "base" are not universally applicable to all three shapes in the context of their volume formulas. The hypotenuse applies to right triangles, while "base" can refer to different aspects depending on the shape.
So the correct answers are pi (3.14) and radius.
