Circumference of a circle = pi*diameter
---
The smaller circle's circumference = %28pi%29%2A%281%2F2%29+=+%28pi%2F2%29
Larger circle's circumference = %28pi%29%2A%284%29=4pi
---
The ratio between the circle's circumference is %28pi%2F2%29%3A%284pi%29
---
When simplified the ratio of the circumference of the larger circle to the smaller is 8pi%3Api
