A cylinder has a radius of 5 in. If the volume of the cylinder is 250 pie inches cubed, What is the height of the cylinder?

pi*r^2*h=250*pi

pi cancels. solve for h

r^2*h=250

h=250/r^2??

This is what I got originally.

250=pie(5)squared *h.

250= pie 25 h

10= pie h

h= 10 over pie

so far so good.

What is r? r is 5 inches in the probloem. Substtitute 5 for r, square it, and divide into 250.

"Substtitute 5 for r, square it, and divide into 250."

250/25=10

so, h=10?

right

Okay, so h=10

Do I need to use inches or inches squared?

Do I need to use inches or inches squared?

How do you measure the height of something? I measure it in inches or feet, not inches^2 or feet^2

Okay, great!!!

Thank you so very much for your help! It is truly appreciated!!!!

note that pi is pi and not pie. pi is the Greek letter pi but I can't make that symbol on the computer.

What is the square root of 125?
