radius formula
the real question is how do you figure this out? You want to get everything
except the R on one side of the equation, so: C = 2 * Pi() * R C/2 = Pi() * R You are dividing both sides by 2 C/2/Pi() = R You are dividing both sides by Pi() -- If this helps, please click the Yes button Cheers, Shane Devenshire "joelhmiller" wrote: how do i create a formula to find the radius (circumference=2*3.14r) if i have the circumference? |
