the wheel on jessicas bike has a radius of 13 inches. how many revolutions will the wheel make while jessica travels 500 feet?

Answer 1

Find the circumference of the wheel by doing 2 x pi x r...so 2(3.1416)(13) = 81.68 inches.

Convert 500 feet to inches so we have the same unit...500x12 = 6000 inches.

6000/81.68 = 73.46 revolutions.

Answer 2

r=13 inches

one revolution = the circumference= pid=2pir=26pi inches

500 feet=12(500)= 6000 inches

6000/26pi= 3000/13pi= about 3000/13(3.141593)

= about 73.456 revolutions

= about 73

Answer 3

C = 2πr

500 ft = 6000 in

6000 in / 2πr in = number of revolutions
