Finding Circumference Using the Measure of Area

This video tutorial teaches how to find the circumference of a circle using its area. It begins by reviewing the formulas for area and circumference of a circle, and explains the concept of square roots, highlighting common mistakes. The tutorial provides two examples: one with an exact Pi value and another with an approximated Pi value, demonstrating how to calculate circumference in each case. By the end, viewers will understand how to derive circumference from area, even when Pi is approximated.
