Answer:
the radius must equal 2
Step-by-step explanation:
A = pi * r^2 C = 2 * pi *r
set them equal
pi * r^2 = 2 * pi *r
divide both sides by pi
r^2 = 2 * r
divide both sides by r
r^2 /r = 2r/r
r = 2
2.5 divided by 2 equals 1.25 so each side equals 1.25
If you would like to know how many pounds of pasta the restaurant will need, you can calculate this using the following steps:

The elimination method consist is adding the two equations in a way that one variable be eliminated..
In order to do that you might have to manipulate on of the equations prior to add the two equations.
