Answer:
the area of the small square 4c
the total area of the 4 triangles is 2ab
a^2+2ab+b^2 = a^2+2ab+b^2
subtracting gives 2ab from both sides gives us a^2+b^2

Step-by-step explanation:
hope this helps..........
V=hpir^2
c=2pir
assuming they havve same height
first one is
v=hpi5^2
v=25hpi
2nd one
c=2pir=20pi
2pir=20pi
2r=20
r=10
v=hpir^2
v=hpi10^2
v=100hpi
big/small=100hpi/25hpir=4
4 times greater
Y=2(-1)^2-6(-1)+3
y=2+6+3
y=8+3
y=11
