Answer:
H = 3 r - 5 .
Step-by-step explanation:
Given : The height ,H of a cylinder is 5 units less than 3 times the radius, r.
To find : What is an expression that can represent .
Solution : we have given that
The height ,H of a cylinder is 5 units less than
3 times of radius = 3 *r
H = 3 r - 5 ( negative sign for less than )
Therefore, H = 3 r - 5 .
