Week 5 – Finding the Surface Area and Volume of a Cone

During the fifth week of Foundations of Mathematics and Pre-Calculus 10, I learned to find the surface area and volume of a cone. To determine the surface there is a formula which must be used to calculate the answer (formula in image). When finding the surface area of cones, you must make sure you have all the measurements given. If not, pythagorean theorem must be used to determine the side you are missing. Also, if the diameter is given, find the radius. Next, to determine the volume, you must use a formula (formula in image). Note: volume is the amount of space the object takes up. Pythagorean theorem is not required for this formula. Although, sometimes you must convert your answer to a different unit. When dealing with formulas, on some cases, the volume or surface is given, and you must substitute the formula to find the missing side/length. Remember to always use the full “pi” number, do not round off to the nearest decimal. Apply the formulas below, and you get your approximate or full answer.
