the diameters of your car (including your tires) is 25 inches. You are going to drive 220 miles today. Each of your wheels is going to turn by an angle of __ degrees
what, you drive a round car?
each turn of the wheels is 25π inches, so each mile is 5280*12/(25π) revolutions
Each mile is 25280*12/(25π)*2π radians, or 5068.8 radians
so, 220 miles will be 220*5068.8 = ____ radians
