This can't really be explained.
Two angles are supplementary when they <span>add up to 180 degrees.
x = angle
19x-60 = </span><span>supplement angle
x + 19x - 60 = 180
20x = 180 + 60
20x = 240
x = 240/20
x = 12</span>° ← answer
They would be the same because the formula is volume equals pi radius squared times height. So you would use the radius of 1.5 instead of the diameter of 3
