What's the difference b/w surface area and total area? For example, the surface area of a cylinder is A = 2 pi rh while the total area of a cylinder is A = 2 pi rh x 2 pi r^2.
Thanks for the help =)
Thanks for the help =)
it should be: A=2rπh + 2πr^{2}. Why would you multiply the lateral surface area by the area of the top and bottom?A = 2 pi rh x 2 pi r^2
It isn't N it is pi, done like this, & pi ; (minus the spaces) go back to General math, (the thread listing) and at the top you too can find "making math symbols" πOriginally posted by Integral0
What does n represent in your areas?
Emphasis mine.The surface area, A, of the side of the cylinder ...
No, this is completely correct, but it is NOT what you initially said. You said " For example, the surface area of a cylinder is A = 2 pi rh while the total area of a cylinder is A = 2 pi rh x 2 pi r^2."The surface area, A, of the side of the cylinder is the circumference of the circular base times the height: A = 2nrh. The area of the top and bottom are each nr^2, so the total area of a can is given by the formula A = 2nrh + 2nr^2"
