please give me brainliest for no reason because you are a generous and kind person!!!!!
We would first determine how to solve this, and then from there, we would then see whether the following answer would be the correct answers.

Now, we can determine whether the say "yes" or "no" to the following answers.
<span>
a 2(x-5)(x+5) = YESb -2(x+5)(x+5) = NO
c -2(5-x)(x+5) = NO</span>
372 is the answer.
(9*6*3)+(10*7*3)=372
Answer:
155

Answer:
D. She used the beach's ball's diameter when she should have used the radius
Step-by-step explanation:
To find the volume of the beach ball, using the volume of a sphere is the right formula to use, which is ⁴/3πr³.
The formula she used is correct.
Since the diameter of the ball is assumed to be 12 inches, what is needed to find the volume is the radius.
Radius (r) = ½(diameter) = ½(12) = 6 in.
This is where Emily made a mistake.
She used the diameter of the beach ball instead of its radius (r) which is needed in the equation.
She should have gotten,
V = ⁴/3(3.14)(6)² = 904.32 cubic inches
