Thomas,
A square measures 12 cm x 12 cm and is divided into four equal squares. If equal circles are inscribed within each of the four squares, what is the circumference of each circle ?

math 
Reiny,
So each circle has a diameter of 6 cm or a radius of 3 cm
Circumference of one circle = 2πr
= 2π(3)
= 6π
