1

area of a circle =πr^2
ratio of areas of two circles =4:16
πr1^2:πr2^2
r1^2:r2^2
r1^2=4,r2^2= 16
r1:r2 = 2:4

. Choose the best description of the radial velocity method of locating exoplanets. This method works well for detecting planets orbiting in close proximity to a star, so the planet can more readily observe passing in front of the star. Planets are timed as they orbit distant stars. The size of the planet can be judged by the time duration it takes to transit a star. The orbiting planet causes...
