Radian measure of angle theta s= 2 and r=4
The radian measure of an angle is defined as the length of the arc on the unit circle that corresponds to that angle. In this case, we have s = 2 and r = 4.
The formula for calculating the radian measure of an angle is given by θ = s/r, where θ is the radian measure, s is the length of the arc, and r is the radius of the unit circle.
Substituting the given values, we have θ = 2/4 = 1/2.
Therefore, the radian measure of angle theta is 1/2.
