Question

Circumference of a 4" circle?

Answer 1

Answer:

4π ≈ 12.5663706144

Step-by-step explanation:

The circumference of a circle is 2πr, or 2*pi*radius

Suppose the circle has a diameter of 4 inches. A diameter is 2x the radius, of which we are looking for, therefore:

4÷2=2 inches (radius length)

Now that we have the radius, let us substitute to find the circumference:

2πr=

2π2=

4π≈

12.5663706144
