Best ResponseYou've already chosen the best response.1You're looking for the base of the cylinder? That's a circle, so the formula for area is A=pi*r^2

Best ResponseYou've already chosen the best response.1Maybe I'm misunderstanding the question, but as I read it, none of the answers you posted are correct, since none include pi.

Best ResponseYou've already chosen the best response.1If you want the AREA of the BASE, that won't involve the height. The formula for area of a circle is A = pi*r^2 If your choices all include pi, then yes, the answer is 16 pi sq. units. If you post choices for a multiple choice question, it's important that you post exactly what the choices are. You can just type "pi" if you don't want to use the equation editor, but don't just ignore it.... :)

Best ResponseYou've already chosen the best response.0I'm sorry! I'm new here lol So how would you find the lateral area for the same figure?

Best ResponseYou've already chosen the best response.1The volume of the cylinder would be V = h*pi*r^2 (area of the base x height). I don't think r*h*pi would be.... anything. :)

Best ResponseYou've already chosen the best response.0lol sorry I'm not very good at math. Thanks. But can you help me with one more thing?

Best ResponseYou've already chosen the best response.1Lateral area would be the area of the outside of the cylinder, right? Without the bases. So you need to think of "unrolling" the cylinder. It would be a rectangle then, with height = h =6, and base = circumference = 2pi*r = 8pi.
