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

Hm, I can't understand what they want, lol sorry :/

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

with the specific data I found
anonymous
  • anonymous
Well if you divide the circumference by the diameter, you will get pi
anonymous
  • anonymous
that's the definition of pi itself

oh, I think I get what I need to do
anonymous
  • anonymous
I do that to find pi and see how close it is

with percent error

yep
