Answer:

4.5 inches

Step-by-step explanation:

We are given the formula:

V = $\pi r^{2}h$

Plug in the the radius (3) and volume (127.23):

127.23 = $3.14(3)^{2} h$

Square the 3 :

127.23 = $3.14(9)h$

Multiply the pi & volume:

127.23 = 28.26h

Divide both sides by 28.26:

127.23 ÷ 28.26 = 28.26h ÷ 28.26

h = 4.5021231...

I hope this helps!
