Acircle has the equation (x-2)^2 +y^2 =5. what are the coordinates of the circle's center?

Brook states that the distance on the line is 4 units. caleb states that the whole line does not have a distance because it continues on forever. vivian states that the line is 6 units long. which distance did brook measure? which distance did vivian measure?

True or false? a circle could be circumscribed about the quadrilateral below.
