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?
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.
To rearrange the formula to solve for the radius (r), we need to isolate the variable r. Here's the step-by-step process:
1. Start with the equation: C = 2πr.
2. Divide both sides of the equation by 2π to cancel out the 2π on the right side of the equation:
C / (2π) = r.
3. The equation is now rearranged to solve for the radius: r = C / (2π).
So, if you are interested in finding the radius of the circle, you can use the formula r = C / (2π).
To rearrange the formula to find the radius of the circle, we need to isolate the variable "r" on one side of the equation.
The given formula is C = 2πr, where C represents the circumference and r represents the radius of the circle.
First, divide both sides of the equation by 2π to isolate the "r" variable:
C / 2π = 2πr / 2π
This simplifies to:
C / 2π = r
So, the rearranged formula to find the radius of the circle is:
r = C / 2π
