Answer:
952 cubic feet
Step-by-step explanation:
The diameter is 21, so the radius is 10.5. The area of a circle is πr^2, so 10.5^2π, or 110.25π. The pool is filled 9 inches from the top, so it is 3.5 feet - 9 inches high, 9 inches is 0.75 feet, so 2.75 feet filled. Now multiply 110.25π by 2.75 to get 303.1875π and then 952.4916, closer to 952 cubic feet.

<h2><u>B.</u></h2>
2 - 7 + 8x -3
Step-by-step explanation:
To multiply a binomial (2 terms) by a trinomial (3 terms):
Multiply the first term of the binomial by the each term of the trinomial.
Multiply the second term of the binomial by each term of the trinomial.
Combine the expressions and simplify.
(2x-3)*(-2x+1)
(2x * ) + (2x * -2x) + (2x * 1)
(2) + (-4) + (2x)
(2x-3) * (-2x+1)
(-3 * ) + (-3 * -2x) + (-3 * 1)
(-3) + (6x) + (-3)
[2 + -4 + 2x] + [-3 + 6x + -3]
2 - 7 + 8x -3
