An artist wishes to paint a circular region on a square poster that is 3 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?	Choose the most appropriate option: A) 1/pi B) sqrt(2/pi) C) sqrt(4.5/pi) D) 2/sqrt(pi) E) pi/2
Area of the poster is 3x3 = 9   1/2 the area = 4.5   pi*r^2 = 4.5   r^2 = 4.5/pi   r = sqrt(4.5/pi) answer (sqrt(4.5/pi))
