2. A water tank is in the shape of a right circular cylinder with a height of 9
feet and a volume of 225 pi cubic feet. What is the diameter of the water
tank? *

Respuesta :

Answer:

10 ft.

Step-by-step explanation:

V = Bh where B = area of the base, which is a circle in your problem.

So, B = [tex]\pi r^{2}[/tex]

225π = π[tex]r^{2}[/tex](9)

[tex]r^{2}[/tex] = 25

r = 5 ft

diameter = 2r = 10 ft.
