    Formulas for circumference and area of a circle, and volume of a cylinder and sphere are introduced, and some calculations are done without using a calculator. This is a great introduction to basic geometric formulas, and how to plug numbers into them.

    Pretty simple all in all but very interesting and well explained. It helped me with putting in the numbers for the formulas.
