Answer:
π= C/2r
Explanation:
In order to solve for pi, we must get pi by itself on one side of the equation.
C= 2πr
Let's rearrange the right side of the equation. We can do this because of the commutative property of multiplication.
C= 2πr
C= 2r* π
pi is now being multiplied by 2r. The inverse of multiplication is division. Divide both sides of the equation by 2r.
C/2r= 2r*π/2r
C/2r= π
π=C/2r
