Question

Two circles are drawn below. The diameter of the smaller circle is the radius of the larger circle. What is the ratio of the smaller circle's circumference to the larger circle's circumference?

Give your answer in fully simplified form. It should look like "x:y", where x and y are replaced by integers.

Answer 1

1:2????

so basically the smaller circle is 50% of the larger circle being 1/2 of it??

(might be incorrect)
