A bricklayer is using a 20.0-in-diameter winch to life pallets of bricks to the roof of a building 45ft above the ground. The rope that lifts each pallet is wrapped around the outer rim of the winch.
(a) Through how many degrees must the bricklayer turn the winch to life the pallet by 1.0 ft?
(b) Through how many revolutions must the winch turn to life a pallet from the ground to the roof?

What the FUCK.

I found the circumference, but that doesn't help.
The height matters for part (b), but I can't figure out (a).

I'm pissed at this. Also, I hate significant numbers.
