Answer:

radius = 1

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

(x - 2)² + (y + 3)² = 1 ← is in standard form

with r² = 1 ( take the square root of both sides )

r = \sqrt{1} = 1
