If the cylinder were dilated using a scale factor of 4, what would be the new surface area? The formula for the surface area of a cylinder is
SA=2πrh+2π

.
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)
