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

Original SA = 2π(8)(15+8) = 2π·8·23 = 368π.
Scaling by factor 4 multiplies area by 4^2 = 16, so new SA = 368π·16 = 5888π cm².

Answer: 5,888π cm².
