Question 660534
What do they mean when they say "Write the equation of a circle with radius equal to square root 2 and center at (2, 5)." I understand how to set up the equations but what's throwing me off is the radius equal to square root 2. What does that mean?
-----
Ans: (x-2)^2 + (y-5)^2 = (sqrt(2))^2
