# Given a cylinder of vertical height, H and radius R. h = H/R

#### isabella

1.)Given a cylinder of vertical height, H and radius R. h = H/R So what does this equation means? what is h?

2.)Given L is the length from the cylinder base to an element at ground level, s = L/R. So what does s stand for?

I am as clueless as you are!

h = ratio of height of the cylinder to the radius of the base??
h = sine of the angle which is made by the line joining the center of the top and a point at the rim of the base with the horizontal (viewing the cylinder as a orthogonal projection in a 2D plane) ??

Maybe you would like to give the question in its entirety?
