Question

If one of the diameters of the circle given by the equation x square + y square - 4 x + 6 y - 1 is

Answer 1

Answer:

diameter= 7.484 cm

Step-by-step explanation:

given the equation is ; x^2+y^2- 4x + 6y - 1=0

solving; x^2 - 4x + y^2 + 6y =1

x^2 - 4x +(2)^2 +y^2 + 6y + (3)^2= 1+4+9

(X -2)^2 +(y +3)^2 = 14

therefore r^2 = 14

r = √14

r = 3.742cm

d= 7.484cm
