It is given that the radius of a circle is 2 units.

We need to find the circumference of the circle.

The formula for circumference of a circle is

where, r is the radius of the circle.

Substitute r=2 in the above formula.

Here,  

Therefore, the circumference of the circle is  or 12.57 units.

to determine the unit cost your would divide the total cost by the number sold.
