The center of a spherical balloon is at a height of \(500\, \mathrm{m}\)
height. The visual angle of the balloon is
\(1^{\circ }30'\). The elevation angle of the
center of the balloon is \(42^{\circ }50'\).
Find the diameter of the balloon in meters and round to nearest one decimal.
\(19.3\, \mathrm{m}\)
\(18.2\, \mathrm{m}\)
\(18.9\, \mathrm{m}\)
\(19.5\, \mathrm{m}\)
