The shape in the middle is a cylinder on its side; the cylinder has length L and radius R; you only need the area of the curved sides (not the "end caps"). The shapes on the end are cones with radius R and height d; you only need the area of the curved sides (not the bases). But what exactly is "h" measuring? I'm not sure??cross section area of this body is a circle with radius R. and the cones at the ends are the same.. write down a procedure to calculate the volume based on h. 0<h<2R

in the routine derivation of the volume of cone by integration ,

it means you have a circular base with the constant radius of R and integrate along the height d(as in the current problem).. in fact we are summing up the volumes of discs along height with the base area of pi*r*r and this must be multiplied by the delta(d) and then we integrate this along height from o to d..

in ths case i am going to keep the height as condstant and integrate along radius... we have some cones that put above each other...

I hope I can explain clearly.

Excuse me buddy..

I didn't ask the exact problem as is..

My question is . suppose this is a water reservoir...

calculate the volume of this reservoir based on h... I mean if we fill the reservoir with water , up to h. how we calculate the volume.

Okay. So this isn't geometry; it's calculus. And you're not doing anything standard like finding the volume of a cylinder in a nice orientation; you're finding the partial volume of a complicated shape in a not-nice orientation. That was important information. (Admin/mods: Please move this to "calculus".)
