You are standing beside the colorado river, 400 feet from the base of hoover dam. using an electrical distance measuring device, you find a distance to the top of the dam to be 965 feet. find the height of the dam

878.1941ft

Step-by-step explanation:

When you are standing in that position, you are making a 90º triangle with the hipotenuse of the trangle being 965 feet, and the base of the triangle would be 400 feet.

The laws of triangles dictate that the sum of both squared sides equals the hiponetnuse squared. The formula would be like this

If you clear the height you´d get:

You clear the height and it will end up like this:

Height=

Height= 878.19 feet.

answer: ok

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
