I would think that this would be an example of what you are looking for. By the way, you are so pretty! :) Sorry if I am wrong, I will try again if you don't think it is right.
Step One
Begin by getting one side of the question equal to zero.
32x -4 = 4x^2 + 60 Add - 32x + 4 from both sides.
0 = 4x^2 + 60 - 32x + 4 Collect like terms.
0 = 4x^2 - 32x + 64
Step Two
For this question, you could divide both sides by 4. It just makes the steps later on easier.
0 = x^2 - 8x + 16
Step Three
Calculate the discriminate.
The discriminate is b^2 - 4*a*c
a = 1; b = -8; c = 16
b^2 - 4*a*c = (-8)^2 - 4*(1)(16) = 64 - 64 = 0
There is only 1 root. It is real and it is rational.

Answer:
Area of the circle = ![24.618\,feet^2](https://tex.z-dn.net/?f=24.618%5C%2Cfeet%5E2)
Step-by-step explanation:
Radius of the circle= ![2.8\,feet](https://tex.z-dn.net/?f=2.8%5C%2Cfeet)
Area of the circle= ![\pi \times r^2](https://tex.z-dn.net/?f=%5Cpi%20%5Ctimes%20r%5E2)
As,
![\pi =\dfrac{22}{7} =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D%5Cdfrac%7B22%7D%7B7%7D%20%3D3.14)
Area of the circle is:
![=3.14\times 2.8 \times 2.8\\\\= 3.14 \times 7.84\\\\=24.618\,feet^2](https://tex.z-dn.net/?f=%3D3.14%5Ctimes%202.8%20%5Ctimes%202.8%5C%5C%5C%5C%3D%203.14%20%5Ctimes%207.84%5C%5C%5C%5C%3D24.618%5C%2Cfeet%5E2)
The Area of the circle is : ![24.618\,feet^2](https://tex.z-dn.net/?f=24.618%5C%2Cfeet%5E2)
Answer:
Area = 16π
Step-by-step explanation:
Area of a circle = πr^2
= 64π
= sqrt64
r = 8 because 8 × 8 is 64
Radius = 8
Now, use the circumference equation:
= 2πr
= 2π(8)
= 16π
