Need help with triq word problem

A car wheel has a 14 inch radius. Through what angle (to the nearest tenth of a degree) does the wheel turn when the car rolls forward 5 ft?



A pulley rotates through 52 degrees in one minute. How many rotations does the pulley make in an hour?

C=2*pi*r=2*pi*14 =360°
5*12/(2*pi*14)=x/360

52°/1 min = x°/60 min
rotations = x/360°
