To find the circumference of a circle the equation is 2 times pi times the radius. The radius is half of the diameter, so its 12. So the answer would be 75.36mm

Answer:

Circumference = 75.36 mm.

Step-by-step explanation:

Given  : A quarter has a diameter of approximately 24 millimeters.

To find : What is its circumference.

Solution : Diameter =  24 mm.

Radius =  [tex]\frac{Diameter}{2}[/tex].

Radius =  [tex]\frac{24}{2}[/tex].

Radius =  12 mm

Circumference = 2 * pi* radius .

Plugging values

Circumference = 2 * 3.14* 12 .

Circumference = 75.36

Therefore, Circumference = 75.36 mm.
