Mrs. Sue. Thank you for your words of kindness and not putting me down when I had a question. I have looked through your site and I do ind that you certainly are reputable. I apologize for my rudeness to you yesterday and I confessed to my mom. Whew! I feel better now. I do have a different question about Algebra. We were goig over different fomulas for 3D pictures. I became very confused when a questions was asked differently. It had to do with the finding the lateral area of a cone. What is the difference of a lateral area and the surface area? Also, do they use the same formula. We can use formulas from our folder but when the words are mixed I get confused. Thank you for your help.

google is your friend. This is but one of many discussions on the topic.
