To find the circumference of a button, you can use the formula for the circumference of a circle:
[ C = pi times d ]
where ( C ) is the circumference and ( d ) is the diameter.
Given that the diameter ( d ) is 8 millimeters:
[ C = pi times 8 ]
Using ( pi ) approximately equal to 3.14:
[ C approx 3.14 times 8 ]
[ C approx 25.12 text{ mm} ]
So, the correct answer is A 25.12 mm.
