Question

The orbit of Venus is nearly circular. An astronomer develops a model for the orbit in which the Sun has coordinates (-5, 20). The circular orbit of Venus passes through (62, 20), and each unit of the coordinate plane represents 1 million miles. Which equation represents the orbit of Venus according to this astronomer?

a. (x + 62)2 + (y + 20)2 = 3844
b. (x - 5)2 + (y + 20)2 = 3844
c. (x + 5)2 + (y - 20)2 = 4489

Answer 1

its C
by distance between two points you can find the radius.
that is 67
now equation of circle is
(X-h)^2 + (Y-k)^2= R^2
where (h,k) is the center of circle
and R is the radius

Answer 2

thanks!
