2(12j + 4) = 56
Answer: Her refund would be $5,681.20.
The problem says that Laura paid the estimate above, which is 28%.
0.28 x 134350 = 37618
However, she had some deductions.
134350 - 4000 - 12200 - 4090 = 114060
So, to find the tax on this amount, we multiply it again by 0.28.
0.28 x 114060 = 31936.8
The amount of the refund will be the difference.
37618 - 31936.8 = 5681.2
Area shaded = Area big circle- Area of small circle;
200 pi= pi•(2x)^2 -pi•6^2;
200pi= pi•4x^2 -pi•36;
200pi=pi•4(x^2 -9) divide both sides by 4pi;
50=x^2 -9; So x=sqrt(59)~7.68cm
