The 10 is the diameter and you need the radius to do it so you do diameter dived by 2 which gives you the radius then you the radius to the power of 2
so the formula would be (3.14)(5)²(6)

Answer:
![2x^3-5x^2-7x-2](https://tex.z-dn.net/?f=2x%5E3-5x%5E2-7x-2)
Step-by-step explanation:
1) Expand by distributing sum groups.
![2x(x^2-3x-2)+x^2-3x-2](https://tex.z-dn.net/?f=2x%28x%5E2-3x-2%29%2Bx%5E2-3x-2)
2) Expand by distributing terms.
![2x^3-6x^2-4x+x^2-3x-2](https://tex.z-dn.net/?f=2x%5E3-6x%5E2-4x%2Bx%5E2-3x-2)
3) Collect like terms.
![2x^3+(-6x^2+x^2)+(-4x-3x)-2](https://tex.z-dn.net/?f=2x%5E3%2B%28-6x%5E2%2Bx%5E2%29%2B%28-4x-3x%29-2)
4) Simplify.
![2x^3-5x^2-7x-2](https://tex.z-dn.net/?f=2x%5E3-5x%5E2-7x-2)
Thanks!

Answer: B
Step-by-step explanation:
To get no solution you need to have 2 sides of the equations that don't match. If you go through B you will end up getting 3x- (11/7)=3x-2 which is not true.
A function with a zero in a is,
![f(x)=x-a](https://tex.z-dn.net/?f=f%28x%29%3Dx-a)
So,
