# Math 7 - NYS Math Exam Review - Book 1 (HW)

C = 2nr!?!??!??!

Since the NYS Math Exam is coming up (in my district in my school we have it next week). You see in my class were not done with our geometry and ratio, proportion unit and plus we are missing one unit: algebra. We didn't get to solving the formulas. Ratio and proportion I think were done with that unit idk.... Over the spring break we are required to do this workbook (ALL OF IT). I'm almost done with it though.
Algebra I learn a lot I guess bcuz she assign us pages in our work book and I usually do the problems with my mom. Anyways there is this geometry problem about C = 2nr. I don't remember how to solve this in order. Can you teach me how to solve C = 2nr please or is there a website that shows step-by-step on how to solve it plus with an example.

Thank You! :)

I think you mean:

Circumference = 2 * pi * radius
