The formula of the volume of a sphere is (4*pi/3)*R^3. You said you know how calculate the ratios. Can you continue from there?
Planet Aniram is similar to Planet Semirg, both of which are perfect sphere. If the ratio of the length of Planet Aniram’s radius to the length of Planet Semirg’s radius is 3:4, then find the volume of Planet Semirg in cubic units if the volume of Planet Aniram is 135 cubic units.
I know how to find the ration, you divide by 3 but I don't know how to find the volume in cubic units.
Does not matter what the form of similar simple solids is the volume scales as the cube of any linear dimension. So if the radii are in the ratio the volumes are in the ratio .
The condition that they are both perfect spheres is redundant, that they are similar is sufficient.
