Best ResponseYou've already chosen the best response.1lateral area of a cylinder formula: \[lateral surface area of a cylinder = 2\pi r h\]

Best ResponseYou've already chosen the best response.2If you cut the cylinder, and unrolled it, it would look like a rectangle. one side would be the (unrolled ) circumference of the circle, and the other side would be the height. The problem becomes: find the area of a rectangle.

Best ResponseYou've already chosen the best response.0You use the hight of the cylinder as the length of the rectangle

Best ResponseYou've already chosen the best response.0and the diameter as the width. or is it the other way around?

Best ResponseYou've already chosen the best response.2not the diameter, the circumference (distance around) take a piece of paper and roll it to form a cylinder (with no top or bottom) It should be clearer what is going on. as for which side is height vs width of the rectangle, it's arbitrary what we call each side.

Best ResponseYou've already chosen the best response.0Okay. Is the lateral area the same thing as surface area or no? I'm just wondering

Best ResponseYou've already chosen the best response.2lateral (Latin for side) is the "side area" of the cylinder.... the part you can paint, but not including the top and bottom "circles" on a can of peas (for example), the lateral area is where the label goes.

Best ResponseYou've already chosen the best response.0Oh that makes so much more sense! Oh My Gosh! I was thinking that lateral area was just another term for surface area

Best ResponseYou've already chosen the best response.2surface area usually means the *entire* surface (which means for a cylinder you add in the area of the top and bottom)
