Find the dimensions of the largest cylinder that can be inscribed in a cone of fixed height H and fixed radius R

To find the dimensions of the largest cylinder that can be inscribed in a cone with a fixed height H and fixed radius R, we can use geometric reasoning.

Let's assume the cone is placed on a table with its base at the bottom. The largest cylinder that can be inscribed in the cone will have its base tangent to the base of the cone. This means that the radius of the cylinder will be equal to the radius of the base of the cone.

To determine the height of the cylinder, we need to consider that the apex of the cone acts as the top point of the cylinder. So, the height of the cylinder will be equal to the height of the cone.

Therefore, the dimensions of the largest cylinder that can be inscribed in the cone will have a height of H and a radius of R.

In summary, the dimensions of the largest inscribed cylinder in the cone with fixed height H and fixed radius R are H (height) and R (radius).
