I don’t know the answer I need point because this app makes me answer these when I don’t know them just for me to get them wrong and not be able to do them correct and fail just y=mx+b it is 6 and 7
Answer: First option is correct.
Step-by-step explanation:
A number in an expression is a term that contains no variables.
So, it is known as constant term.
if any term is with variable or variables, then it can't be consider as a number.
Then, it becomes only a term.
But if there is no variables in a term is present, then it is called to be number.
Hence, First option is correct.

Answer:
The area is
![A=254.34\ in^2](https://tex.z-dn.net/?f=A%3D254.34%5C%20in%5E2)
Step-by-step explanation:
The circumference of a circle is given by a following formula:
![C = 2\pi r](https://tex.z-dn.net/?f=C%20%3D%202%5Cpi%20r)
Where r is the radius of the circumference.
In this case we know that
![C = 2\pi r=56.52\ in](https://tex.z-dn.net/?f=C%20%3D%202%5Cpi%20r%3D56.52%5C%20in)
We solve the equation for r
![C = 2\pi r=56.52\ in](https://tex.z-dn.net/?f=C%20%3D%202%5Cpi%20r%3D56.52%5C%20in)
![2\pi r=56.52\\\\r=\frac{56.52}{2\pi}\\\\r=9\ in](https://tex.z-dn.net/?f=2%5Cpi%20r%3D56.52%5C%5C%5C%5Cr%3D%5Cfrac%7B56.52%7D%7B2%5Cpi%7D%5C%5C%5C%5Cr%3D9%5C%20in)
The area of a circumference is given by the following formula
![A=\pi r^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2)
Now we substitute the value of r in the equation to find the area
![A=\pi (9)^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20%289%29%5E2)
![A=3.14* (9)^2](https://tex.z-dn.net/?f=A%3D3.14%2A%20%289%29%5E2)
![A=254.34\ in^2](https://tex.z-dn.net/?f=A%3D254.34%5C%20in%5E2)
