From MathWorld--A Wolfram Web Resource. http://mathworld.wolfram.com/Cone.html See more WebNow “r” is a function of “h” so. h = H − H R r. d h = − H R d r. Substituting the same in the above equation we get the integral as. ∫ R 0 π r 2 ( − H) R d r. V o l u m e = π 3 R 2 H. If you do the same process for the surface area you will end up getting. S u r f a c e A r e a = π R H. Which is not true.
