An artist wishes to paint a circular region on a square poster that is 4 feet on a side. If the area of the circular region is to be 1/2 the area of the poster, what must be the radius of the circular region in feet?	Answers:  A) 1/pi  B) sqrt(8/pi)  C) 1  D) 2/sqrt(pi)  E) pi/2
Area of the poster is 4x4 = 16   1/2 the area = 8   pi*r^2 = 8   r^2 = 8/pi   r = sqrt(8/pi) answer : 1
