Jason decorated the outside of the cylinder what is the surface area of the cylinder in square inches

a.72
b. 78
c.192
d. 260​

Answer 1

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
