Question: See the previous question for the formula for computing the angular size of an object as observed from some particular distance. The red-orange star

See the previous question for the formula for computing the angular size of an object as observed from some particular distance. The red-orange star Betelgeuse, located on the shoulder of Orion, has a diameter 1000 times the diameter of the Sun, where the Sun's diameter D = 1.4 million kilometers. Betelgeuse is located d = 640 light years away, where 1 light year = distance traveled in one year at light speed, and light speed c = 300,000 kilometers per second. What is the angular diameter of Betelgeuse, expressed in percents of an arcsecond? Calculate your answer in arcseconds, multiply by 100 to get a percentage, and enter in the blank: The angular diameter of Betelgeuse is how many % of an arcsecond?
