Write the standard equation of the circle with center (-5, 2) and radius 1.3.

(x+5) 2 + (y-2) 2=1.69

(x-5) 2 + (y+2) 2=1.69

(x+5) 2 + (y-2) 2=16.9

(x-5) 2 + (y+2) 2=16.9

    (x + 5) ² + (y - 2) ² = 1.69

    Step-by-step explanation:

    The equation of a circle in standard form is

    (x - h) ² + (y - k) ² = r²

    where (h, k) are the coordinates of the centre and r is the radius

    Here (h, k) = ( - 5, 2) and r = 1.3, thus

    (x - ( - 5)) ² + (y - 2) ² = 1.3², that is

    (x + 5) ² + (y - 2) ² = 1.69
