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

Solution:

The circumference is a closed curve where all points are at the same distance from the center.

The circumference of a circle is its boundary or the length of the complete one of a circle.

Calculate the circumference of a circle is by using the formula 2 π r, where r is the radius of the circle.

⇒ 2 π r = 2 π × 4 = 8 π

You can also use circumference of circle calculator,

Thus, the circumference of a circle with a radius of 4 is 8 π.
