Question

Use the distance formula to find the radius of a circle, given that the center is at (2,-3) and the point (-1,-2) lies on the circle.Round your answer to the hundredth place

Answer 1

the distance formula is \[d=\sqrt{(y_2-y_1)^2+(x _{2}-x_1)^2}\]

Answer 2

lets the first point be (x1,y1) and the second point be (x2,y2)

Answer 3

now substitute and then tell me what you get
