8, the radius is half of the circumference.

The formula to find circumference of circle is given by :

[tex] C = 2\pi r [/tex]

Where r is radius of circle.

We are given radius as 4 units here.

Also we take pi as 3.14

plugging these values in the equation to find circumference,

[tex] C = 2* 3.14 * 4 [/tex]

C =25.12 units

So circumference of the circle is 25.12 units.
