90 in terms of pi is .
<u>Step-by-step explanation:</u>
We know that ,
- Degrees are a unit of angle measure. A full circle is divided into 360 degrees. For example, a right angle is 90 degrees. A degree has the symbol ° and so ninety degrees would written 90°. Another unit of angle measure is the radian.
- The radian is the SI unit for measuring angles, and is the standard unit of angular measure used in many areas of mathematics. The length of an arc of a unit circle is numerically equal to the measurement in radians of the angle that it subtends; one radian is just under 57.3 degrees.
We have to convert 90 in terms of pi i.e. degree to radians:

Therefore, 90 in terms of pi is .
