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?
Responses
•
r=Cπ/2
•
r=C/π
•
r=2πC
•
r=C/2π
r=C/2π
To rearrange the formula to find the radius of the circle, divide both sides of the equation by 2π.
Therefore, the correct rearrangement of the formula is:
r = C/2π
To rearrange the formula to solve for the radius (r), we need to isolate r on one side of the equation.
Given the formula C = 2πr, we can divide both sides of the equation by 2π to get:
C / 2π = r
Therefore, the correct rearranged formula to find the radius of the circle is:
r = C / 2π
