Use the image to answer the question.

A cylinder has a height of 15 centimeters and a radius of 8 centimeters.

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+2πr2

Work: under dilation by 4, surface area scales by 4^2 = 16. Original SA = 2π(8)(15)+2π(8^2)=240π+128π=368π. New SA = 16·368π = 5888π cm².
