Q:
Write an equation in standard form for the circle shown.A) (x + 3)2 + (y β 1)2 = 7 B) (x - 3)2 + (y + 1)2 = 7 C) (x + 3)2 + (y β 1)2 = 49 D) (x - 3)2 + (y + 1)2 = 49
Accepted Solution
A:
radius = 7
center = (-3, 1)
Equation for a circle is: rΒ² =Β (x-h)Β² + (y-k)Β²
where r = radius, (h,k) = center
fill in the values to get:
7Β² = (x+3)Β² + (y-1)Β²
Answer is C
