If the diameter of semi circle is AB then,
C is a point on AB such that a perpendicular is drawn from it which intersects the circumference of circle at E. if ac=2 and CE=6 find area of circle bounded

• let center be P
  then cp = r-2
  PE = radius
  apply pythagoras
  r^2 = 6^2 + r^2 + (r-2)^2
  r = 10
  area = 50pi
  50pi

• CE is perpendicular on AB. so just join E with center of the circle (O) and find EO, which is sqrt(40). So area is (pi*40)
