An artist is making a square stained glass window in which a
green
g
lass circle is surrounded by
blue glass. The side length of the window is 20x, and the area of
the green piece is 64πx^2
.
What i
s the area of the blue glass? Write your answer in factored form.
so far i have Area 1= 400x^2 and Area 2= π(64πx^2)^2 and the GCF is 16x^2, am i right? can someone help me finish?

i think that the are of blue glass is given by the subsequent difference:
$$\Large 400{x^2} - 64\pi {x^2}$$

michele_laino · Answer

now, please try to factor out 16x^2, what do you get?

kearsten · Answer

16x^2(25-4pi)?

michele_laino · Answer

that's right!
