An artist wishes to paint a circular region on a square poster that is 3.4 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 choice from the following options
A) 1/pi	B) sqrt(2/pi)	C) 1	D) 2/sqrt(pi)	E) sqrt(5.78/pi)
Area of the poster is 3.4x3.4 = 11.56   1/2 the area = 5.78   pi*r^2 = 5.78   r^2 = 5.78/pi   r = sqrt(5.78/pi) answer (sqrt(5.78/pi))
<result>E</result>
