A car tire has a diameter of 70 cm. The tire rolls without sliding along a road. Let x be the distance (in cm) the car travels as the tire rotates 0 radians. Assume to be positive and consider only its magnitude. (So, its position on the circle is not relevant.) Assume also that the distance x is positive. x (a) Find as a function of x. Use exact values in the formula, not decimal approximations. 0(x) = (b) If the car rolls forward 44 cm, what is the angle that the tire rotates (in degrees)? Round your answer to the nearest tenth of a degree. 0=0° DO x e G
