Question

The volume of a cylindrical soup can is represented by the expression πr3 + 7πr2, where r is the radius of the cylinder. Which statement best interprets the factor (r + 7) in this context? Hint: The volume of a cylinder is given by the general formula V = πr2h, where h is the height of the cylinder.

Answer 1

pir^3 + 7pir^2
=  pir^2 ( r + 7)
comparing this with pir^2h we see that r + 7 = height of the cylinder.

Answer 2

Answer:

Step-by-step explanation:

The height of the cylinder is 7 units greater than the radius.
