Yes, it would be extremely cold at -20F.
General equation of a circle on the Cartesian plane: x^2+y^2 +2gx+2fy+c = 0 Points: (2, 0) (3, 1) (-6, 10) Substitute the above values into the general equation:- 4g+c = -4 6g+2f+c = -10 -12g+20f+c = -136 Solving the above simultaneous equations: g = 2, f = -5 and c = -12 General equation is now: x^2+y^2 +4x-10y-12 = 0 Completing the squares: (x+2)^2+(y-5)^2 -4-25-12 = 0 So: (x+2)^2+(y-5)^2 = 41 Therefore centre of circle is at: (-2, 5) and its radius is the square root of 41 Proof: Distance from (-2, 5) to any of the given points equals to the square root of 41
You are asking about a 20 Franc coin from Belgium. Coins from Belgium were issued both in French and in Dutch (actually, Flemish) - your coin is Flemish (French coins refer to "Belgique" rather than "Belgie"). 60,000,000 "Belgie" 20 Franc coins were produced in 1981 (and a further 60,000,000 "Belgique" as well), and one is worth about US$0.70 in Extremely Fine condition and about US$2.00 in Uncirculated condition.

-20F is colder than -20C. This is because the Fahrenheit scale has a smaller degree interval than the Celsius scale, so -20F is a lower temperature than -20C.
It is about 20F and -7C.
