A 24 foot ladder is placed against a building at an angle of 75⁰. How far is the bottom of the ladder from the building?

yanalaym [24]

24ft is the hypotenuse, at an angle of 75<span>⁰, and we need to find the adjacent.

We use cos(), which is adjacent divided by hypotenuse.

Therefore, we can find the adjacent by doing:

25 * cos(75) = 6.47ft

Round the answer however you like.</span>

The radius of a cylindrical water tank is 5.5 ft, and its height is 13 ft. What is the volume of the tank?

mezya [45]

Answer:

1235 ft³

Step-by-step explanation:

Volume of a Cylinder: 2πr²*h

π = 3.14

r = 5.5 ft

h = 13 ft

Volume = 2(3.14)(5.5)²*13 = 1235.43 ft³
