How to get surface area of a cone using integral calculus?
2018年4月9日 · Please see below. . Let's look at the following figure and define parameters: The apex of the cone is on the origin. OC=h is the vertical height of the cone and lies on the x-axis. OB=l is the lateral (slant) height of the cone. CB=r is the radius of the base and is parallel to the y-axis. In between the the blue vertical lines: dx=dh a small increment in the vertical height of …
