    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}
