( x + 18 )² + ( y + 7 )² = 12²
( x + 18 )² + ( y + 7 )² = 144
Is the equation correct?
A circle has a diameter of 12 with a center translated 18 units left and 7 units down from the origin.
1. Write an equation for the circle.
(x + 18) ^2 + (y + 7)^2

I am sure Bosnian meant:
( x + 18 )² + ( y + 7 )² = 6² , since the radius is 6, not 12
( x + 18 )² + ( y + 7 )² = 36
( x + 18 )² + ( y + 7 )² = 6² , since the radius is 6, not 12
( x + 18 )² + ( y + 7 )² = 36
