An experiment measuring nuclear radii via high-energy electron scattering finds that the radius of an oxygen-16 (816O^{16}_{8}\text{O}816O) nucleus is 3.04 × 10-15 m.
Assuming that the density of nuclear matter is constant, what is the expected radius of a thorium-232 (90232Th^{232}_{90}\text{Th}90232Th) nucleus?
