Convert $\pi$ into degrees.

$180^{\circ}$

$90^{\circ}$

$30^{\circ}$

$360^{\circ}$

$3.14^{\circ}$

Explanation

Recall that there are 360 degrees in a circle which is equivalent to $2\pi$ radians. In order to convert between radians and degrees use the relationship that,

$360^\circ=2\pi \Rightarrow 180^\circ=\pi$ .

Therefore, in order to convert from radians to degrees you need to multiply by $\frac{180}{\pi}$ . So in this particular case,

$\pi*\frac{180}{\pi}=180^{\circ}$ .

Convert $\pi$ into degrees.
