The figure above shows the shape and dimensions of the inside of a container that has a flat rectangular top and semicircular ends perpendicular to the top. When the container is loaded to its exact capacity.( i.e. leveled off on top) with slag that weighs 50 pounds per cubic foot, what will be the approximate weight, in tons, of the slag in the container?

Does it have to do anything with right triangle?

Find a volume of a half-cilinder

V/2=1/2*(16pi*10)=80pi cubic feet

Slag weighs 50 pounds per cubic foot

Mass of slag = pi*80*50=4000pi pounds.

1 pound = 400 grams

Mass=1 600 000 pi grams=1 600 pi kilograms=1.6 pi tons = 5 tons approximately.
