The circumference of the nickel is 6.28 cm.

Important information:

Diameter of a nickel is 2 centimeters.

Circumference:

The circumference of a circle is:

C= 2 π r

C= π d

Where dd is the diameter and r is the radius.

Substituting π = 3.14, d = 2 , we get

C=(3.14)(2)

C=6.28

Therefore, the circumference of the nickel is 6.28 cm.
