The general form of the equation of a circle is x2 + y2 + 42x + 38y − 47 = 0. the equation of this circle in standard form is (x + 21)^2 + (y + 19)^2 = 849 .
the center of the circle is at the point a(-19, -21) b(-21, -19) c(19, 21) d(21, 19) , and its radius is a. 127^(1/2) b. 849^(1/2) c. 851^(1/2) d. 47 units.
the general form of the equation of a circle that has the same radius as the above circle is a. x^2 + y^2 + 60x + 14y + 98 = 0 b. x^2 + y^2 + 44x - 44y + 117 = 0 c. x^2 + y^2 - 38x + 42y + 74 = 0 d. x^2 + y^2 - 50x - 30y + 1 = 0 . someone with those 3 multiple choice ones.
