Solve for C C(r)=2pir

$C (r) = 2 π r$

Step 1

Divide each term in $C r = 2 π r$ by $r$ .

$\frac{C r}{r} = \frac{2 π r}{r}$

Step 2

Simplify the left side.

Cancel the common factor of $r$ .

Cancel the common factor.

$\frac{C r}{r} = \frac{2 π r}{r}$

Divide $C$ by $1$ .

$C = \frac{2 π r}{r}$

$C = \frac{2 π r}{r}$

$C = \frac{2 π r}{r}$

Step 3

Simplify the right side.

Cancel the common factor of $r$ .

Cancel the common factor.

$C = \frac{2 π r}{r}$

Divide $2 π$ by $1$ .

$C = 2 π$

$C = 2 π$

$C = 2 π$

Step 4

The result can be shown in multiple forms.

Exact Form:

$C = 2 π$

Decimal Form:

$C = 6.28318530 \dots$
