Formulas have been important in previous math courses and will definitely come in handy as you learn Geometry. Whether you are attempting to calculate the perimeter or the area of a figure, you'll need to remember the formulas to arrive at the correct answer. Today's free Geometry video is on Using Formulas in Geometry and will cover the basic formulas you've most likely encountered already in your math education. In the first lecture, Professor Burger focuses on perimeter, or the sum of the side lengths of the figure. He also covers area, the number of non-overlapping square units of a given size that exactly cover the figure. In the second lecture he applies formulas for perimeter and area in a word problem. In the third, and final, lecture Professor Burger covers more formulas, circumference and area of a circle. The circumference of a circle is the distance around the circle. Get ready for our good friend Pi to make an appearance in these formulas.

Don't forget that today's video has a total of three lectures on it. Click the forward button directly to the left of the time stamp to move to the next lecture on the video so you don't miss a word!
