Hoover dam on the colorado river casts a shadow that is 2,904 feet long. at the same time, an 18-foot-tall flagpole next to the dam casts a shadow that is 72 feet long. how tall is the hoover dam?

  726 feet

Step-by-step explanation:

Object height and shadow length are proportional, so you have ...

  (object height)/(shadow length) = (18 ft)/(72 ft) = (dam height)/(2904 ft)

Then the dam height is ...

  dam height = (2904 ft)(18/72) = 726 ft

Hoover Dam is 726 feet high.

step-by-step explanation:

1. the cylinder is a. 54
