# What angle is 1.30 pi in radians?

Sep 6, 2015

Assuming you meant what angle in degrees is $1.30 \pi$ radians:
$1.30 \pi \text{(radians)} = {234.0}^{\circ}$

#### Explanation:

$\pi \text{ (radians)} = {180}^{\circ}$

$1.30 \pi \text{( radians)} = 1.30 \cdot {180}^{\circ} = {234.0}^{\circ}$

An angle specified as a real number (like $1.30 \pi$) is assumed to be in radians, so an angle of $1.30 \pi$ is an angle of $1.30 \pi$ radians.

Also, in the unlikely event that you meant:
What angle is 1.30pi^@ in radians?
$\textcolor{w h i t e}{\text{XXXX}} {1}^{\circ} = \frac{\pi}{180}$ radians
$\rightarrow \textcolor{w h i t e}{\text{XXXX}} 1.30 {\pi}^{\circ} = \frac{1.30}{180} {\pi}^{2}$ radians
