Each) 1) Give the equation of a circle with the center (2,-3) and radius =2. Sketch its graph and label 4 coordinates points on the X and Y axis where the circle lies. 2) If the radius of a circle is increased and the measure of the central angle is held constant, what happens to the length of the intercepted arc? Illustrate by a drawing based on the result of the solution given radius = 1,2,3 with central angle equals 45 degree. Show solution neatly and drawing should be properly labeled.
