Irodov Problem 1.343

Suppose that the height, radius and the slant length of the code in a reference frame stationary with respect are code be h, R and L respectively. When the cone moves along the axis, the vertical height to h' shrinks to

but the radius R will remain the same.

a) Hence we have,

The lateral surface area of the cone is given by
