Question

Solve the equation C=2πr for π

Answer 1

C = 2πr   Divide both sides by 2r
$\frac{C}{2r}$ = π   Switch the sides to make it easier to read
π = $\frac{C}{2r}$

Answer 2

Answer:

The value for $\pi=\frac{C}{2r}$

Step-by-step explanation:

Consider the provided equation.

C=2πr

Now we need to solve the above equation for π.

Divide both the side of the equation by 2.

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

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

Now divide both the sides by r.

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

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

Hence, the value for $\pi=\frac{C}{2r}$
