Answer:
13.345
Explanation:
The formula to calculate the circumference is simply C = πd
It doesn't get simpler than that. Let's check the formula
Circumference = Pi * Diameter
Now let's check the numbers that we've got
The Diameter is 4.25
π is approximately 3.14
4.24 * 3.14 = The number that we're looking for
Now we do the math and we have:
4.24 * 3.14 = 13.345
The Circumference of the hole is 13.345
