The height, h, of a cylinder is 5 units less than 3 times its radius, r. Which expression represents the height of the cylinder in terms of its radius?

5-3r
3r-5
5h-3r
3r-5h

The height, h, of the cylinder is 5 units less than 3 times its radius, r.

This can be represented as h = 3r - 5.

Therefore, the expression that represents the height of the cylinder in terms of its radius is 3r - 5.

So, the correct answer is 3r - 5.
