What is the circumference of a circle with a diameter of 4?

Here we will show you how to calculate the circumference of a circle with a diameter of 4.

Diameter means the straight line distance from one side of a circle to the other side of the circle passing through the center. In this case it is 4. Furthermore, the circumference is the distance around the circle.

The formula to calculate the circumference if you know the diameter is as follows:

Circumference = Diameter x π

π = Pi = 3.14, thus, the math to calculate the circumference of a circle with a diameter of 4 is:

4 x 3.14 = 12.56

And the answer to the circumference of a circle with a diameter of 4 is approximately:

≈ 12.56

We shortened Pi to two decimal points which is why the answer is just approximate. Pi goes on indefinitely: 3.14159265359.... The more decimal points you use for Pi, the more accurate your answer will be.
