Answer:
250 square inches.
Step-by-step explanation:
The surface area of a cylinder is given by:
[tex]S=2 \pi \: rh + 2\pi{r}^{2} [/tex]
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:
[tex]S=2 \times 3.14 \times 3 \times 10 \: + 2 \times 3.14 \times {3}^{2} [/tex]
[tex]S=244.92[/tex]
The surface area is approximately 250 in²
