I would divide 113.1/3.14(which is pi) to find out what is the diameter
what do you get ?

something way off. 36.02

ivettef365 · Answer

ok diameter of larger circle = 36, so the ration of diameter is 3:5 that is equal to 3/5 = 0.60, so what is 36 x .60 =  (that would be diameter of smaller circle)

anonymous · Answer

21.6 round and i get 22. 6 thanks :)

ivettef365 · Answer

wait, that is not the answer yet

ivettef365 · Answer

the question is what is the circumference of the smaller circle, now you have the diameter of the smaller circle = 21.6, so the circumference is the diameter x 3.14 so
21.6 x 3.14
