Answer:

250 square inches.

Explanation:

The surface area of a cylinder is given by:

$S=2 \pi \: rh + 2\pi{r}^(2)$

From the diagram, the radius of the cylinder is r=3 in. and the height is h=10 in.

We substitute the radius and height to get:

$S=2 * 3.14 * 3 * 10 \: + 2 * 3.14 * {3}^(2)$

S=244.92

The surface area is approximately 250 in²
