I know it is a silly question, but when the question says the solid rotates 4 right angles, is it 360 degrees or 180 degrees. This is because I thought it was 360 degrees, but when looking at the answer, it works out as 180 degrees, for three questions now! Please help!!!

Lol,

Right angle = 90 degrees...

So 4 right angles = 4*90 = 360 degrees.

Where the hell did you get 180 from?
