The document provides instruction on calculating the circumference and area of circles. It includes examples of word problems involving finding radius, diameter, circumference, and area when given one of the other measurements. Students are asked to solve the problems using a pi button and including units in their final answers rounded to the nearest hundredth. The document aims to teach the relationships between radius, diameter, circumference and area of circles through examples.
