A race car is driven around a circular track at a constant speed of 180mph. If the diameter is 1/2 mile, what is the angular speed of the car? Express your answer in revolutions per hour.
The formula for angular speed is w=theta (in radians)/time

Find the value of each of the remaining trig functions.
Cscθ=4, π< θ<3π/2
