A wheel of radius 1.9 feet is moving forward at 12 feet per second. How fast is the wheel turning?

Find the circumference to see how much of the wheel is touhing the ground

c=2pir

c=2pi1.9

c=2.8pi

2.8pi=distance per 1 rotation

number of rotations per second times 2.8pi=12feet per second

dvide both sides by 2.8pi

number of rorations per second=12/2.8pi

number of roations per second=6/1.4pi

number of roations per second=3/0.7pi

number of roations per second=30/7pi

aprox

number of roations per second=1.364 rotations per second
