ANSWER
![{x}^{2} + 6x + 9](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%2B%206x%20%2B%209)
EXPLANATION
The given expression is
![{(x + 3)}^{2}](https://tex.z-dn.net/?f=%20%7B%28x%20%2B%203%29%7D%5E%7B2%7D%20)
We rewrite to obtain,
![= (x + 3)(x + 3)](https://tex.z-dn.net/?f=%20%3D%20%28x%20%2B%203%29%28x%20%2B%203%29)
We expand using the distributive property to obtain,
![= x(x + 3) + 3(x + 3)](https://tex.z-dn.net/?f=%20%3D%20x%28x%20%2B%203%29%20%2B%203%28x%20%2B%203%29)
This gives us,
![= {x}^{2} + 3x + 3x + 9](https://tex.z-dn.net/?f=%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%203x%20%2B%203x%20%2B%209)
This simplifies to,
![= {x}^{2} + 6x + 9](https://tex.z-dn.net/?f=%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%206x%20%2B%209)
The correct answer is the first option.
Answer:
16π cm²
Step-by-step explanation:
circumference = 2πr
Area = πr²
We need to determine r to calculate the area
2πr = 8π
Divide both sides of the equation by 2π to find r
r = 4
Now, we determine area.
area = πr² = π4² = 16πcm²
