Q: An average dimension for the radius of an atom is 1.0 x 10^-8 cm, and the average radius of the nucleus is 1.0 x 10-^13 cm. Determine the ratio of atomic volume to nuclear volume. Assume that the atom is spherical. [V=4/3(pi)r^3]

I already have the volume for both, but how can I determine their ratios?

"Ratio of A to B" means A/B.

You want atomic volume/nuclear volume then divide.
