By viewing a full moon, you will find that the moon's diametersubtends an angle of about 9.5 degrees. (This means that twolines drawn from your eye to opposite edges of the moon have anangle of 0.5 degrees between them) . The distance from thesurface of the earth to the center of the moon is about 59 earthradii

a) Find the radius of the moon in terms of earthradii

b) How far from your eye would you need to hold a dimeto just barely cover the Moon? (Does the with of your thumbcover the moon if you hold your arm out straight? The moon is nextfull on Sept 18, but a partial moon is enough to judge thediameter.)
