Stuck on cylinder formula question.

Physics
Tutor: None Selected Time limit: 1 Day

The question is:

The formula for the volume of a cylinder is V=pi r^2h.    If V= 2100m^3 and h= 17.0m, find r.

So far I have, 2100m^3= pi r^2x17.0m

                      2100m^3=17r^2m pi



I am stuck on what to do after the last step I have done.

Thank you for the opportunity to help you with your question!

2100=pi*17*r^2

r^2=2100/17pi

r^2=39.34

r=sqrt(39.34)

r=6.27 m

Please let me know if you need any clarification. I'm always happy to answer your questions.

What happened with the m^3 after the 2100?

okay u r not getting units.

if u have any physics question ask me directly

see,

m^3=pi*m*m^2

m^3=pi*m^3

it gets cancelled.
