cylinder sitting atop of it. To find the volume, would i just have to find the volume of the rectangle V=LWH, and then the volume of the cylind (pi)(r)squared(h), and then divide by 2 since it was only half a cylinder?

and yes, i know to add the two together

Find the volume of the cuboid(a 3D rectangle) and the whole cylinder. DIVIDE ONLY THE VOLUME OF THE CYLINDER BY 2. Then add it to the cuboid's volume.

if the l is 4 and the w is 5 and the h is 3 then the volume is 60 if the r is 4 then it is 16 times 3.14 and that is 50.26 and the height is 5 than multiply that with the 50.26 and that is 251.3 and if it is half a cylinder than divide by 2 then add the two volumess together

The best i could figure yes you would find the rectangles volume and cylinders volume(divided by 2) and add them together.

No, if you want the volume of the whole area, you need to add the 2 together.
