A pole stands vertically inside a triangular park $$ABC$$. Let the angle of elevation of the top of the pole from each corner of the park be $$\frac{\pi}{3}$$. If the radius of the circumcircle of $$\triangle ABC$$ is 2, then the height of the pole is equal to :
Let the height of the pole be
$$h$$
and let the foot of the pole be at point $$P$$ inside triangle $$ABC.$$
Given that the angle of elevation of the top of the pole from each vertex is
$$\frac\pi3$$
From vertex $$A,$$
$$\tan\frac\pi3=\frac{h}{AP}$$
$$\sqrt3=\frac{h}{AP}$$
$$AP=\frac{h}{\sqrt3}$$
Similarly,
$$BP=\frac{h}{\sqrt3}$$
and
$$CP=\frac{h}{\sqrt3}$$
Hence,
$$AP=BP=CP$$
Therefore, point $$P$$ is the circumcenter of triangle $$ABC.$$
Thus,
$$AP=R$$
where $$R$$ is the circumradius.
Given,
$$R=2$$
Hence,
$$\frac{h}{\sqrt3}=2$$
$$h=2\sqrt3$$
Therefore, the height of the pole is
$$\boxed{2\sqrt3}$$
