18. find the radius of a cylinder with a volume of 470.48 feet3 and height of 6.5 feet.

V = pi * r^2 * h
V = 470.48
h = 6.5
(pi) = 3.14
now sub

470.48 = 3.14 * r^2 * 6.5now divide both sides by 6.5(pi)
470.48 / 6.5(3.14) = r^2 
470.48 / 20.41 = r^2
23.05 = r^2take sqrt of both sides, eliminating ^2
sqrt 23.05 = r
4.8 = r < ur radius is 4.8 ft

The answer is mathg.a.y

Idon't know what's the answer lol
