The number of visible stars in the night sky, \(T,\) can be estimated by the formula
\(T=\left(\dfrac{4\pi*L^2}{A}\right)N\)
where \(N\) is the number of stars counted through a tube with length \(L,\) in centimeters, a mouth of area \(A,\) in square centimeters. Based on the formula, what is the estimated number of visible stars in the night sky if \(240\) stars are observed through a tube \(10\) feet long with a mouth of radius of \(4\) feet? (\(1\) foot \(= 30.48\) centimeters)
A. \(182,880\)
B. \(7,000\)
C. \(6,000\)
D. \(5,800\)
E. \(500\)
