A thin piece of wire 40 meters long is cut into two pieces. One piece is used to form a circle with radius r, and the other is used to form a square. No wir is left over. Which of the following represents the total area, in square meters, of the circular and the square region, in terms of r:
a) πr^2
b) π^2 +10
c) πr^2 +1/4 π^2r^2
d) πr^2+(40-2πr)^2
e)πr^2 +(10-1/2 πr)^2
a) πr^2
b) π^2 +10
c) πr^2 +1/4 π^2r^2
d) πr^2+(40-2πr)^2
e)πr^2 +(10-1/2 πr)^2
