Given:

The diameter of the baseball is 3in.

To find:

The surface area of the baseball.

Step-by-step explanation:

Since the diameter of the baseball is 3in.

The radius of the baseball is,

$\begin{gathered} r=(d)/(2) \\ =(3)/(2) \\ r=1.5in \end{gathered}$

Using the surface area formula of the sphere,

$\begin{gathered} SA=4\pi r^2 \\ =4*\pi*1.5^2 \\ =9\pi in^2 \end{gathered}$

Therefore the surface area of the baseball is,

$9\pi in^2$

Final answer:

The surface area of the baseball is,

$about\text{ }9\pi in^2$
