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?
A. 5-3r
B. 3r-5
C. 5h-3r
D. 3r-5h
In the question they tell us that the height of a cylinder 5 units less than 3 times its radius, r. Thats why it is subtracted the 5 units to the multiplication of 3r, which is basically 3r-5
