Convert 65 degrees to an equivalent number of radians

$$65\ensurement{^{\circ}}\cdot
\left( \dfrac{\pi}{180\ensurement{^{\circ}}} \right)\\\\
=\dfrac{65\ensurement{^{\circ}}}{180\ensurement{^{\circ}}}\cdot\pi\\\\
=\dfrac{65\not{\ensurement{^{\circ}}} }{180\not{\ensurement{^{\circ}}} }\cdot\pi\\\\
=0.36111111111\cdot\pi\\\\
=0.36111111111\cdot3.14159265359\;\rm{rad}\\\\
=1.13446401380\;\rm{rad}$$
