What is the surgace area of a cylindrical ring or torus if its outside diameter is 16mm andits inside diameter is 10mm?
To find the surface area of a cylindrical ring or torus, you can use the formula A = 2πrh, where r is the average radius of the ring and h is the height or thickness of the ring. In this case, the average radius is (16mm + 10mm)/2 = 13mm and h can be any desired value. Therefore, the surface area of the cylindrical ring or torus is 2π(13mm)(h).
How do you calculate the area of a ring?
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.
Where can one find a ring sizing chart?
One can find a ring sizing chart at many jewelry stores. Each store will have a poster of what each ring size means and how big each ring size actually is.
