Question

Convert angle in radian to degree-

$\frac{\mathrm{\pi }}{2}$

Short answer

The required value is,

$\frac{\mathrm{\pi }}{2}radian=90°$

Step-by-step solution

Step 1. Given information

To convert $\frac{\mathrm{\pi }}{2}$radian to degree.

Step 2. Calculation

Converting from radian to degree,

$$\begin{gathered} \frac{\mathrm{\pi }}{2}radian=\frac{\mathrm{\pi }}{2}.1radian \\ =\frac{\mathrm{\pi }}{2}.\frac{180}{\mathrm{\pi }}degrees \\ =\frac{180}{2}degrees \\ =90° \end{gathered}$$
