Question 123

The degree measure of 1 radian $$\pi=\frac{22}{7}$$ is

Solution

We know that, $$\pi$$ rad = 180°

=> $$1 rad = \frac{180^{\circ}}{\pi}$$ = 57.2727°

=> Converting to minutes = $$(0.2727 \times 60)$$ = 16.36200'

=> Converting to seconds = $$(0.362 \times 60)$$ = 21.72"

=> 1 radian = 57°16'22" (approx)
