Question

Chariot races reached their peak in popularity in ancient Rome around the 1st and 2nd centuries A.D. A chariot wheel had a radius of about one foot. One lap around the track in the Circus Maximus was approximately 2,300 feet. How many chariot-wheel revolutions did it take to complete one lap?

2300 revolutions

341 revolutions

230 revolutions

366 revolutions

Answer 1

The circumference = 2 pi r

(or 2 * radius * 3.14)

so 2 * radius = 2 foot * 3.14 = 6.28

Once you know the circumference you divide the distance by this to work out the number of revolutions:

2300 / 6.28 = 366.

Answer 2

one revolution of a wheel is 3.14 x 1 x 1 = 3.14 feet.

You can do the rest.

Answer 3

im 89 persents its 230 and 11 persent its 341 go with 230 revalutions
