If the ring is 2 cm in diameter, the US ring size is 10 and a quarter. In terms of British and Australian size, it is said to be U.
The diameter is 25/pi cm = 7.96 cm

The volume of a sphere with a diameter of 25cm is about 8181.2cm3
Its area is: pi*52 = 25*pi or 78.539 cm to three decimal places

The ring is 455 cm in diameter. It is centered on a square that is 670 cm on each side. The surface is hard packed clay.
50 cm is the diameter.
The diameter is 25/pi cm = 7.96 cm
Radius = Diameter/2 = 25 cm.
Radius = 1/2 of the diameter = 12.5 cm.
Diameter = 2*Radius = 2 cm.
Diameter of ring=34.1/3.414=9.9cm ( approx 10 cm)
45 cm
Its radius will be half of its diameter and so 50/2 = 25 cm
