Question

Solve for pi : C = 2 pi r

Answer 1

Answer:

π= C/2r

Step-by-step 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

Answer 2

Answer:

$\frac{C}{2r}$=pi
