The radius of a circle is 8units. What is the circumference?

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.
