A thin piece wire 40 meters long is cut into two pieces.
One piece is used to form a circle radius r,and the other is used to form a square.
No wire is left over.which of thr follwing represnts the total area in squre meters of the circular and the square regions in terms of r?
Pai*(r^2)
Pai*(r^2)+10
Pai*(r^2)+1\4(pai^2)(r^2)
Pai*(r^2)+(40-2pai*r)^2
Pai*(r^2)+(10-1\2*pai*r)^2
