How long it takes a bell to ring 11 times depends on how long each ring is and the time in between the rings. For example, if the length of the ring is 10 seconds and there are 2 seconds between the rings, it would take less time than if the rings were 15 seconds with 3 seconds between rings.

Treat the ring as a circle. Area equals pi (3.14) times the radius squared. Whether you take the inner of the ring or the outer of the ring, rather depends on how thick the ring is - inner is probably best as that should loosely match the thickness of the finger on which the ring will eventually sit.
