A US dime (equivalent of 10 cents) is about 17.91 mm in diameter. This is equivalent to approximately 0.7 inches.
Since a radius is equal to one half of the diameter, the radius of a dime is:
17.91/2 = 8.955 mm
So, the radius of a dime is 8.955 mm.
You can use this value to calculate the circumference and area of a dime too by using the following formula:
Circumference = 2 x pi x r
= 2 x 3.14 x 8.955
= 56.24 mm
Area = pi x r2
= 3.14 x (8.955)2
= 251.80 mm2
A dime only weighs 2.268 g and is 1.35 mm in thickness. It also has 118 reeds on its edges.
It is made up of copper with 8.33% nickel.
