Question 1114729
1. Anthony is biking around a circular track in jamming to some tunes. His 
bike tires are 2 feet in diameter, and the track is 1000 feet in diameter. How many times do Anthony’s tires go around one lap around the track?
circumference of the tire:: pi*d = 2pi ft.
# of revolutions = 1000/(2pi) = 500/pi is approximately 159.15

2. In modern cataract surgery (eye surgery) the ophthalmologist( eye doctor) makes an incision that is 6% of the circumference of the cornea. If the diameter of the patients cornea is 8 mm what is the length of the incision?
