Question

convert the angle 2.5 radians to degrees, rounding to the nearest 10th.

Explanation:

Step1: Recall conversion factor

$\pi$ radians = 180 degrees, so 1 radian = $\frac{180}{\pi}$ degrees

Step2: Calculate degrees

$2.5 \times \frac{180}{\pi} \approx 2.5 \times 57.2958 \approx 143.2$

Answer:

143.2
