Let’s check out your problem:

Skyler climbs a watchtower to guard against forest fires.$\newline$The function $R(h)=\sqrt{13h}$ gives the distance, in kilometers, that Skyler can see when their eyes are $h$ meters above the ground.$\newline$The function $A(d)=\pi d^{2}$ gives the area, in square kilometers, that Skyler can guard when they can see a distance of $d$ kilometers.$\newline$Which expression models the area Skyler can guard when their eyes are $h$ meters above the ground?$\newline$Choose $1$ answer:$\newline$(A) $13\pi h$$\newline$(B) $13\pi h^{2}$$\newline$(C) $\sqrt{13\pi h^{2}}$$\newline$(D) $169\pi h^{2}$
