A cylinder has a radius of 4 inches and a height of 5 inches. If the radius of the cylinder is tripled and the height remains the same to create a new cylinder, what will be the difference in the surface areas of the two cylinders? Answer in terms of Pi.
Answers: 2
Radius 
is 4 inches 
is 3 × 4 = 12 inches [as in the question it is given that the radius of the cylinder is tripled]
of 1st cylinder 
of 2nd cylinder 
The difference in the surface areas of the two cylinders is = 
= (408π - 72π) = 336π sq inches
