Question

Convert the degree measurement to radians. Express answer as multiple of π: 45°A. π/6B. π/4C. π/3D. π/5

Answer 1

Answer:

$45º=\frac{\pi}{4}$

To convert degrees to radians, we use:

$\alpha=\theta\cdot\frac{\pi}{180}$

Where θ is the angle in degrees and α the angle in radians.

Then:

$\alpha=45º\cdot\frac{\pi}{180}=\frac{\pi}{4}$
