Hi bobbym,
Thanks for the help. Can you explain why the x-coordinate of the circle's center is 4.25?
Please give full steps to the answer and hide the answer.
1. A circle is tangent to the y-axis at the point (0,2) and passes through the point (8,0), as shown. Find the radius of the circle.
2. The line y = (x - 2)/2 intersects the circle x^2 + y^2 = 8 at A and B. Find the midpoint of line AB. Express your answer in the form (x,y).
