The new surface area of the dilated cylinder can be found by multiplying the original surface area by the square of the scale factor.
Therefore, the new surface area would be 4^2 times the original surface area.
New Surface Area = (4^2)(2πrh + 2πr^2)
Therefore, the new surface area would be 4^2 times the original surface area.
New Surface Area = (4^2)(2πrh + 2πr^2)
