Question

Write the standard equation for the circle.

center (10, _6), r = 6

A. (x + 10)2 + (y _ 6)2 = 6

B. (x + 6)2 + (y _ 10)2 = 36

C. (x _ 10)2 + (y + 6)2 = 36

D. (x _ 10)2 + (y + 6)2 = 6

Answer 1

the main equation the circle is (x-a)^2 + (y-b)^2 = R²,
so the answer must be C. (x _ 10)^2 + (y + 6)^2 = 36
