So you need two basic equations here. The volume of a right circular cone is $\frac{1}{3}bh$ and the volume of a sphere is $\frac{4}{3}\pi{r^3}$ . Use the given information to set these two equal to each other and simplify.

You should tell the reader what $b$ means here, its
not introduced in the question or described in you response.

Ok. Ok. b represents the area of the base, which is circular in this case and can be found by $A=\pi{r^2}$
