Sotoday we learned about lateral area and surface area! :) lateral area is sides only the word "lateral" means sides. formula for lateral area is LA= ph. p= perimeter of the base H= height. formula for surface area is ph+2B. The formulas for a cylinder are LA= 2(3.14) r^2 h and SA=2(3.14)r^2+2(3.14)rh :) homework for tonight is Page 531problems 1-17 23&24
