Question

An angle measure of 91 degrees is equivalent to ____ radians. Round your answer to the nearest hundredth when necessary.

Answer 1

The conversion factor of degrees to radians of the measure of an angle is,
180° = π rad
Using this in the dimensional analysis,
(91°) x (π rad/ 180°) = 91π/180 rad
Hence, the answer is approximately equal to 1.59 rad.
