Given:

The diameter of the hemisphere is 15 inches.

To find:

The surface area of a hemisphere.

Explanation:

The radius of the hemisphere is

[tex]r=\frac{15}{2}inches[/tex]

Using the formula of the surface area of a hemisphere,

[tex]\begin{gathered} S.A=2\pi r^2 \\ =2\times3.14\times(\frac{15}{2})^2 \\ =353.25 \\ \approx353square\text{ }inches \end{gathered}[/tex]

Final answer:

The surface area of the hemisphere is 353 square inches.
