Distance and scale

Using the Orrery, look at one of the planet discs. Putting one end of a
ruler or tape measure on the centre of the Sun disc and the other end in
the centre of the planet disc, measure the distance between the centre of
the Sun and the centre of the disc you have chosen.

Can you find this information on the disc?
Uranus is 19.6 times further from The Sun than Earth.
Neptune is 30.7 times further from The Sun than Earth.
Pluto is 40.4 times further from The Sun than Earth.
How far away would they be on our Orrery model?
