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 can divide both sides of the equation by 2π:
C = 2πr
C ÷ 2π = 2πr ÷ 2π
C ÷ 2π = r
Therefore, the formula to find the radius of the circle would be:
r = C ÷ 2π
To rearrange the formula to find the radius of the circle, we need to isolate the variable 'r'.
The formula for the circumference of a circle is:
C = 2πr
To find the radius (r), we can follow these steps:
Step 1: Divide both sides of the equation by 2π:
C / (2π) = r
Step 2: Simplify the equation on the left side, if possible:
r = C / (2π)
Thus, to find the radius of a circle using the formula for the circumference, you would rearrange the formula as:
r = C / (2π)
To rearrange the formula to solve for the radius (r), we can follow these steps:
Step 1: Start with the given formula: C = 2πr
Step 2: Divide both sides of the equation by 2π. This will eliminate the coefficient (2π) in front of the r.
C / (2π) = (2πr) / (2π)
Step 3: Simplify the equation by canceling out the π terms:
C / (2π) = r
Step 4: Rewrite the equation with the radius (r) isolated on one side:
r = C / (2π)
So, if you rearrange the given formula, you can find the radius (r) by dividing the circumference (C) by 2π.
