You can solve for volume using radius or diameter.
Sphere Volume   = <span>  4/3 • <span>π <span>• r³ <span>    =     <span>( <span>π <span>•d³)/6
We're given the diameter so let's use that.
Volume = PI * d^3 / 6
</span></span></span></span></span></span></span>
<span>Volume = 3.14159 * 3.0^3 / 6
</span>
<span>Volume = 3.14159 * 9 / 2

</span><span><span><span><span>Volume = </span>14.137 cubic centimeters
 </span></span></span>

Answer:

2(4x−1)(4x−1)

Step-by-step explanation:

first you find the GCF of all of the terms, which is 2 because 32, 16, and 2 are all divisible by 2. Then you are left with 2(16n^2-8n+1). Now you factor the rest of it and you are left with 2(4x−1)(4x−1)
