Answer 8

. A cylindrical container weighs 36 ounces. Another container made out of the same material is similar to the first container with a height that is three-fourths the height of the first container. To the nearest tenth of an ounce, how much does the second container weigh?

Answer 9

I think its 27 oz

Answer 10

The height is the only change. As the thickness (radius or diameter) doesn't change, this is a simple pro rata query.

3/4 the height, with the same radius, is 3/4 the weight. Therefore the answer is 3/4 of 36 = 27 ounces.

The answer is different if the diameter changes, but that has not happened here.
