Devon's bike has wheels that are 27 inches in diameter. After the front wheel picks up a tack, Devon rolls another 100 feet and stops. How far above the ground is the tack?
I did all my work carefully but the answer seems wierd.
circumference of tire :84.78 inches
total distance traveled is 1200 inches
1200 /84.78 = 14.154
84.78 : 0.154 = 360: X
X = 0.653
13.5cos0.653 = 13.4991
13.5 - 13.4991 = 0.000876
answer : 0.000876
