At a speed of 22 revolutions per minute, how long will it take a wheel of radius 10,
rolling on its edge, to travel 10 feet? (assume p equals 22/7, and express answer to
nearest 0.1 second.)

Well, if the radius is 10, then the circumference is
What's the unit? Either way, 22 rev. per minute means each minute you go by units per second. Now you got the linear speed, just find out the time by dividing the distance by the speed!
So, what's the unit for the radius?

y = 180 - 63-36-13 = 68 degrees

Z = 180-68-13 = 99 degrees

X = 180 -63-36 = 81 degrees
