Apply Riemann integrals to physics: Find the location of the CM of a right cone of radius R and height H. (b) Intersect the right cone by a horizontal plane. The part of the cone below the plane is called a truncated cone. Without integration, find the location of the CM of the truncated cone. Use R and a for the radii of the truncated cone and h for its height. (c) (Optional) Now intersect the original cone by an inclined plane and remove the part of the cone below the plane. This will create an oblique cone. Find the location of the CM of this cone.
