Answer: 16π units
Step-by-step explanation: To find the circumference of a circle, start with the formula for the circumference of a circle.
Circumference = 2πr
Notice that our circle has a radius of 8 units, so we can plug 8 in for the radius in our formula.
Circumference = (2) (π) (8 units)
Circumference = 16π units
Therefore, the circumference of the circle is 16π units.
