337It can be understood that 750 feet is the answer which is 250 pi feet approx. There is no units. So answer should be d.
69I tried out the sum with radius of the front wheel as 30 feet and the radius of the back wheel as 36 feet. Then by applying formula (C = 2Ï€r), we get the circumferences. Then continuing with the problem, we get the answer as 1800 feet or Option C.
