Answer: Circumference = 20π inches
Step-by-step explanation: To find the circumference of a circle, start with the formula for the circumference.
Circumference = 2πr
In this problem, we are given the radius of the circle which is 10 cm so we can plug 10 cm in for the radius in our formula.
Circumference = (2) (π) (10 in.)
Circumference = 20π inches
