An artist wishes to paint a circular region on a square poster that is 2.4 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?	Choose the correct answer:	A) 1/pi	B) sqrt(2.88/pi)	C) 1	D) 2/sqrt(pi)	E) pi/2
Area of the poster is 2.4x2.4 = 5.76   1/2 the area = 2.88   pi*r^2 = 2.88   r^2 = 2.88/pi   r = sqrt(2.88/pi) answer (sqrt(2.88/pi))
