Really simple problem, so can someone help me out! I appreciate it! I had to measure the radii, circumferences, and areas of some circles. I put the data into a table and was asked to graph the radius (cm) to Circumference (cm). I did so and then it asked me to find the experimental equation. I know that the accepted is A=2pir, so what is the experimental? Thanks a lot!

    or how do I find the experimental I should say.

    Suppose on y you graph circumference and on x you graph radius then we will get a straight line of equation \[y=mx+c\] Since this straight line passes through origin, c=0 we have \[y=mx\] \[2\pi.r=mr\] Where m is the slope using this you can find the slop as 2pi, I'm not sure if this is what they are asking

    They want an equation with another number that is similar, as I am also asked to find percent error.

    after I find the experimental equation

    but is there a way to calculate something like pi that can replace it?

    with the specific data I found

    Well if you divide the circumference by the diameter, you will get pi

    that's the definition of pi itself

    I do that to find pi and see how close it is
