HELP PLEASE!!
As the second hand of the clock rotates the large gear turns 40 degrees. AE = 7 inches, and CD = 5 inches. AC, the length of the chain between the gears is 23 inches. How far does the chain around the circumference of the large gear move to the nearest tenth of an inch? (Enter only the number.)

Best ResponseYou've already chosen the best response.4if you split 360 into parts of 40

Best ResponseYou've already chosen the best response.4right so 40 is 1/9th of 360

Best ResponseYou've already chosen the best response.4you can also split the circumference which belong to the 360 degrees in 9 ways so u can see how much of that circumference belongs to each 40 degrees
