The tires on a bicycle have a diameter of 70 centimeters. About how far does the bicycle travel each time the tires make 10 complete revolutions? A 11 meters O B 22 meters Oc 38 meters 0 44 meters​

Respuesta :

A tire travels the length of its circumference after 1 revolution.

If it’s diameter is 70 cm, it’s radius is 35 cm, or 0.35 meters.

Use the formula for circumference:

C = 2(pi)(r) —> C = 2(pi)(0.35) = 0.7(pi) = 2.2 meters

2.2 meters * 10 revolutions = 22 meters
