Rise/run or change in y/change in x so 3/2
On the unit circle the hypotenuse is always one so we can say:
sinα=y/1 and cosα=x/1 so
The point corresponding the the angle 600° is:
(cos600, sin600) which is approximately
(-1/2, -√(3/4)
Since the outside is 1.5 to 1, we take half of the value of the inside diameter and add it to itself to get the smallest value needed. 0.5+0.25=0.75
So the smallest diameter possible would be 0.75 inches.
<h3>11√2 is the right answer.</h3>
