Answer:

The height of cylinder = 7 inches

Step-by-step explanation:

The formula of a volume of a cylinder:

[tex]V=\pi r^2H[/tex]

r - radius

H - height

We have

r = 5 in

V = 175π in³

Substitute:

[tex]175\pi=\pi(5^2)(H)\\\\175\pi=25\pi H\qquad\text{divide both sides by }\ 25\pi\\\\\dfrac{175\pi}{25\pi}=\dfrac{25\pi H}{25\pi}\\\\7=H\to H=7\ in[/tex]
