Question 103523: A wheel has a radius of 8 inches. To reduce wear on the rubber tire, the radius is increased to 10 inches. How many more inches, rounded to 4 significant digits, will the new tire go on each revolution? Answer by checkley75(3666) (Show Source):
You can put this solution on YOUR website! CIRCUMFERANCE=2PIR=2*3.14*8=50.24 INCHES.
CIR.=2*3.14*10=62.8 INCHES.
62.8-50.24=12.56 INCHES MORE PER REVOLUTION.
