The button on Carey's jacket has a diameter of 8 millimeters. What is the button's circumference?
Ahat [919]

Answer:

25.12 millimeters is your answer.

Step-by-step explanation:

Circumference can be solved by using the equation:

c = 2πr or c = πd

Note that diameter (d) is equal to 8. Plug in 8 for d.

c = (8)(π)

Also note that π = 3.14. Multiply

c = (8)(3.14)

c = 25.12 millimeters.

25.12 millimeters is your answer.
