$\frac{0.7}{2}$

Step 1

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

$(\frac{0.7}{2}) \cdot \frac{180 °}{π}$

Step 2

Cancel the common factor of $2$ .

Step 2.1

Factor $2$ out of $180$ .

$\frac{0.7}{2} \cdot \frac{2 (90)}{π}$

Step 2.2

Cancel the common factor.

$\frac{0.7}{2} \cdot \frac{2 \cdot 90}{π}$

Step 2.3

Rewrite the expression.

$0.7 \cdot \frac{90}{π}$

Step 3

Combine $0.7$ and $\frac{90}{π}$ .

$\frac{0.7 \cdot 90}{π}$

Step 4

Multiply $0.7$ by $90$ .

$\frac{63}{π}$

Step 5

Replace $π$ with an approximation.

$\frac{63}{3.14159265}$

Step 6

Divide $63$ by $3.14159265$ .

$20.05352282$

Step 7

Convert to a decimal.

$20.05352282 °$
