Which of the following radian measures is equal to 90^(@) ? Choose 1 answer: A) (pi)/(3) radians (B) (pi)/(4) radians (C) (pi)/(2) radians (D) (pi)/(6) radians

Set up proportion: To convert degrees to radians, we use the conversion factor that 180 degrees is equal to π radians. Therefore, to find the radian measure equivalent to 90 degrees, we set up the proportion: (90 degrees) * (π radians / 180 degrees).Simplify proportion: Simplify the proportion by dividing both the numerator and the denominator by 90: (90/90) * (π/180/90) = 1 * (π/2) = π/2 radians.Compare with options: Now we compare the result with the given options to find the correct one. π/2 radians is the same as option (C).

Set up proportion: To convert degrees to radians, we use the conversion factor that $180$ degrees is equal to $\pi$ radians. Therefore, to find the radian measure equivalent to $90$ degrees, we set up the proportion: $(90 \text{ degrees}) \times (\pi \text{ radians} / 180 \text{ degrees})$ .
Simplify proportion: Simplify the proportion by dividing both the numerator and the denominator by $90$ : $(\frac{90}{90}) \times (\frac{\pi}{180/90}) = 1 \times (\frac{\pi}{2}) = \frac{\pi}{2}$ radians.
Compare with options: Now we compare the result with the given options to find the correct one. $\pi/2$ radians is the same as option $(C)$ .
