An opaque cylindrical tank with an open top has a diameter of \( 3.00 \mathrm{~m} \) and is completely filled with water. When the setting sun reaches an angle of \( 37^{\circ} \) above the horizon,
\( P \) sunlight ceases to illuminate any part of the bottom of the tank. How deep is the tank (in \( \mathrm{m} \) )?
