If the dimensions of the following cylinder are doubled, what factor will the surface area change by? radius: 8 height: 0.5 2 4 6 8

It would help to find the surface area now, double the dimensions, find the new surface area, and compare.

The surface area of a cylinder is:

2 * pi * r^2 + 2 * pi * r * h

So, the surface area is:

2 * pi * 64 + 2 * pi * 4 = 136 pi

Double the dimensions:

2 * pi * 256 + 2 * pi * 16 = 544 pi

544 pi divided by 136 pi = 4

So, the answer is 4.

ask the math teacher she or he would know lol.
