We will use the FOIL method to solve this.
(7x-7)(x+1)
Multiply 7x by x. Then, multiply 7x by 1. Then, multiply -7 by x. Then, Multiply -7 by 1.

Now, we need to simplify by combining like terms.

If you look, -7x and 7x are gone. This is because they cancel each other out.
I hope this helped and maybe consider giving me brainliest :)
Answer:
523.6 cm^3
Step-by-step explanation:
We know the diameter is 10. The radius is half the diameter, so 10/2=5.
Knowing the radius is 5, we just need to plug it into the formula.
Volume=(4/3)pi5^3
≈523.6
