The W. M. Keck Observatory atop Mauna Kei in Hawaii is a two-telescope astronomical observatory. When first completed, the two Keck telescopes were the largest astronomical telescopes in the world. Each telescope, which is composed of 36 separate hexagonal reflecting elements, has a focal length of 17.5 m. The planet Venus has a radius of 6052 km. When Venus is at a distance of 4.14 × 107 km from the earth, find the diameter of the image of Venus formed by one of the Keck telescopes.
