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.
