$\frac{2 p}{9}$

Step 1

To convert radians to degrees, multiply by $\frac{180}{π}$ , since a full circle is $360 °$ or $2 π$ radians.

$(\frac{2 p}{9}) \cdot \frac{180 °}{π}$

Step 2

Cancel the common factor of $9$ .

Step 2.1

Factor $9$ out of $180$ .

$\frac{2 p}{9} \cdot \frac{9 (20)}{π}$

Step 2.2

Cancel the common factor.

$\frac{2 p}{9} \cdot \frac{9 \cdot 20}{π}$

Step 2.3

Rewrite the expression.

$2 p \cdot \frac{20}{π}$

Step 3

Combine $2$ and $\frac{20}{π}$ .

$p \cdot \frac{2 \cdot 20}{π}$

Step 4

Multiply $2$ by $20$ .

$p \cdot \frac{40}{π}$

Step 5

Combine $p$ and $\frac{40}{π}$ .

$\frac{p \cdot 40}{π}$

Step 6

Move $40$ to the left of $p$ .

$\frac{40 p}{π}$

Step 7

$π$ is approximately equal to $3.14159265$ .

$\frac{40 p}{3.14159265}$

Step 8

Convert to a decimal.
