Question

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

Answer 1

B.) 3r-5

Step-by-step explanation:

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

Hope it helps :>

Answer 2

Three times the radius means
`3r`

5 units less than this means that you have to subtract 5 from this quantity, and you have
`3r-5`
