The equation for a circle is (x - h)^2 + (y - k)^2 = r^2 where (h, k) is the center and r is the radius (x + 8)^2 + (y + 9)^2 = 169 Since the equation is -h and -k, I will rewrite in terms of -h and -k. (x - -8)^2 + (y - -9)^2 = 13^2 The center is (-8, -9) and the radius = 13 Let me know if you need me to explain further.
If you have 1 kilogram of mass, its weight depends on where you take it. On the surface of the moon, it weighs about 5.84 ounces. But on Earth, it weighs about 35.3 ounces.
