The center of a circle is at (2, – 5) and its radius is 12.
What is the equation of the circle?
O (2 – 2)2 + (y + 5)2 = 24
• (x + 2)2 + (y – 5)2 = 24
• (x - 2)2 + (y + 5)2 = 144
(x+2) + (y – 5)2 = 144

Hi there!

The correct answer to this question: (x-2)² + (y-5)² = 144

Step-by-step explanation:

The equation for a circle is (x-h)² + (y-k)² = r²   where the center is (h,k)

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
