Answered by admin @
Concept : if (h,k) is the centre of cirlce and r is the radius of that circle then, equation of cirlce is (x - h)² + (y -k)² = r²
here,
Centre of circle = ( 1/2 , 1/4)
radius of cirlce = 1/12
equation of circle is
(x - 1/2)² + (y - 1/4)² = (1/12)²
x² + 1/4 - x + y² + 1/16 - y/2 = 1/144
x² + y² - x -y/2 + 1/4 + 1/16 - 1/144 = 0
x² + y² - x - y/2 + (36 + 9 -1)/144 = 0
x² + y² - x - y/2 + (44)/144 = 0
x² + y² - x -y/2 + 11/36 = 0
36x² + 36y² -36x - 18y + 11= 0
hence, equation of cirlce is , 36x² + 36y² -36x - 18y + 11 = 0
