The largest wheel of a penny-farthing- the precursor to the modern bicycle - has a diameter of 1.5 meters. If the largest wheel of a penny-farthing has rotated 75 times, about how far has a person on a penny-farthing ridden?
using associative property of multipication which is a(bc)=(ab)c
so c=2 times pi times r c=pi times (2 times r) c=pi times diameter c=pi times 1.5 circumference is 1.5pi multiply by 75 112.5pi is the answer (pi is aprox 3.14 so 112.5 times 3.14=353.25 meters)
the answer is 112.5π meters or aprox 353.25 meters
