c.) The tires of an automobile have a diameter of 22 in. If the wheels revolve 18 times, how many feet does the automobile move?
2 answers:
You use the circumference formula to find the circumference of the tire. Multiply it by 18 Bc it revolves 18x. Then since it was in inches they ask for feet instead so divide the answer by 12 to get your answer. Mine is the exact answer and the question asks for rounding it to the nearest hundredth, just use calculator or replace the pi as 3.14
