The formula for the surface area of a cylinder is
$2\pi rh+2\pi r^(2)$ . Using this, you can calculate that the cylinder's total surface area is 56
$\pi$ . But, since Adrian only needs to find the surface area outside of the tire, I'm going to assume that you only need to apply
$2\pi rh$ to your problem. Therefore, the answer is 24
$\pi$ or 75.4 (rounded to the nearest tenth). I hope this helps!
