A wheel starts from rest and rotates with constant angular acceleration and reaches an angular speed of 12.0 rad/s in 3.00 s. Find the angle (in radians) throuh which it rotates in this time.

clearly a = (12rad/s)/(3s) = 4 rad/s^2
As with linear motion, s = 1/2 at^2, so it traveled through
1/2 * 4 * 9 = 18 rad
