The diameter of a circle has length 12. The center is at (-5,2) . Give the equation of the circle?
1 answer:
9514 1404 393
Answer:
(x +5)² +(y -2)² = 36
Step-by-step explanation:
The radius is half the diameter, so is 12/2 = 6.
The standard form equation for a circle is ...
(x -h)² +(y -k)² = r² . . . . . . circle centered at (h, k) with radius r
For the given parameters, the equation is ...
(x +5)² +(y -2)² = 36
