Best ResponseYou've already chosen the best response.1The equation (for circles at the center) in general is: x^2 + y^2 = r^2 All you have to do is substitute in for the "r".

Best ResponseYou've already chosen the best response.03 square root of 3 squared. What would that equal?

Best ResponseYou've already chosen the best response.0The standard form is x^2 + y^2 = r^2 3sqrt3 is equal to 27. Square the 3, which is 9. Then the sqrt of 3 which is just 3.

Best ResponseYou've already chosen the best response.1So, (9)(sqrt(3))^2

Best ResponseYou've already chosen the best response.0Since the center is at 0,0 you don't need to change the x2 or y2

Best ResponseYou've already chosen the best response.1And (sqrt(3))^2 = 3

Best ResponseYou've already chosen the best response.1so, (3)^2 x (sqrt(3))^2 = 9 x 3 = 27

Best ResponseYou've already chosen the best response.1So, you have: x^2 + y^2 = (3 x sqrt(3))^2 x^2 + y^2 = 27
