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

Answer:

π·r^3 + 7·π·r^2 = r^2·π·(r + 7)

r + 7 is the height of the cylinder.
