Given:
The diameter of the baseball is 3in.
To find:
The surface area of the baseball.
Explanation:
Since the diameter of the baseball is 3in.
The radius of the baseball is,
[tex]\begin{gathered} r=\frac{d}{2} \\ =\frac{3}{2} \\ r=1.5in \end{gathered}[/tex]
Using the surface area formula of the sphere,
[tex]\begin{gathered} SA=4\pi r^2 \\ =4\times\pi\times1.5^2 \\ =9\pi in^2 \end{gathered}[/tex]
Therefore the surface area of the baseball is,
[tex]9\pi in^2[/tex]
Final answer:
The surface area of the baseball is,
[tex]about\text{ }9\pi in^2[/tex]
