In anthropology and geography, a cultural region, cultural sphere, cultural area or culture area refers to a geographical area with one relatively homogeneous human activity or complex of activities (culture). culture area is a concept in cultural anthropology, in which a geographic region and time sequence (age area) is characterized by substantially uniform environment and culture.
Venus is closer to the sun than any other planet except Mercury. Its mean (average) distance from the sun is about 67 million miles (108 million kilometres).
Once this Earth-Venus distance is known, the distance between Earth and the Sun can be calculated. As you have indicated, once the distance between Earth and Sun is known, one can calculate all the other parameters. We know that the Sun, as seen from Earth, has an angular diameter of about 0.5 degrees. Again, using trigonometry, the radius or diameter of the Sun can be calculated from the distance between Earth and Sun, a, as 2ÃR sun = tan(0.5 degrees) Ã a.
