To rearrange the formula to find the radius of the circle, we need to isolate the 'r' term on one side of the equation. The current formula is:
C = 2πr
To find 'r', we can divide both sides of the equation by 2π:
C / (2π) = (2πr) / (2π)
This simplifies to:
r = C / (2π)
Therefore, by rearranging the formula, we find that the radius of the circle is equal to the circumference divided by 2 times π.
Given the formula for the circumference of a circle, C=2πr, how would you rearrange the formula if you were interested in finding the radius of the circle?
