Prompt

The table shows the volume of two similar solids, right circular cylinder A and right circular cylinder B. The radius of right circular cylinder A is 3 units. The surface area of right circular cylinder A is

k π

square units, and the surface area of right circular cylinder B is

nπ

square units, where

k

and

n

are constants. What is the value of

n - k

? (The surface area of a right circular cylinder with radius

r

and height

h

2 π r^{2} + 2 π r h
