To determine which three-dimensional figure does not have a "B" in its corresponding volume formula, let's look at the volume formulas for each figure:
- Cylinder: The volume formula is \( V = B \cdot h \), where \( B \) is the area of the base.
- Pyramid: The volume formula is \( V = \frac{1}{3}B \cdot h \), where \( B \) is the area of the base.
- Sphere: The volume formula is \( V = \frac{4}{3} \pi r^3 \); there is no base area \( B \) involved in this formula.
- Cone: The volume formula is \( V = \frac{1}{3}B \cdot h \), where \( B \) is the area of the base.
From this analysis, the figure that does not have a "B" in its volume formula is the sphere.
