We are given a cone whose radius is 15 inches and slant height is 25 inches. We need to solve for its surface area.

To find the surface area of a cone, we use the following formula:

$SA=\pi rl+\pi r^2$

where r = radius and l = slant height.

Let's substitute the given.

$\begin{gathered} SA=\pi(15)(25)+\pi(15^2) \\ SA=375\pi+225\pi \\ SA=600\pi \end{gathered}$

The answer is 600 square inches.
