A wheel has a radius of 15 cm. Approximately how far does it travel in 4 revolutions?(Will medal and fan!) A.47.1 cm B.94.2 cm C.188.4 cm D.376.8 cm

OpenStudy (anonymous):

if it has a radius of 15, multiply that by 2 to get 30, which is your diameter. Circumference = diameter*pi = 30Pi = 94.2. In four revolution (94.2*4) it would have traveled 376.8
