Meka plans to bake a large circular cookies for her brothers. She wants to decorate the outer edge of the cookie small pieces of choclate. The radius of the cookies is 7 inches.What would be the closest to the curcumference of the cookie?

Math 
Reiny,
circumference = 2πr
= 2π(7) = 14π
That is the "exact" value of the circumference.
