The circle below is centered at the point (3, 1) and has a radius of length 2.
what is its equation?

b

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) = (3, 1) and r = 2, hence

(x - 3)² + (y - 1)² = 2², that is

(x - 3)² + (y - 1)² = 4 → b
