A circular dashboard of radius 1.0 foot is at a distance of 20 feet from you. You throw a dart at it and it hits the dartboard at some point Q in the circle. What is the probability that Q is closer to the center of the circle than the periphery? (a) 1.00 (b) .75 (c) .25 (d) .50

• .25
  because the area of the circle with half radius 'r/2' is 1/4th of the area of circle with radius r
