5 is correct! the real answer is 4.80
Answer:
9π OR 28.26
Step-by-step explanation:
The formula for circumference is C = 2πr.
Substitute circumference = 18.84 for C.
18.84 = 2πr
Work backwards to find the radius of your circle.

r = 3
Now, use the formula for the area of a circle: A = π
.
Substitute r = 3 into the equation:
A = π
= 9π ≈ 28.26
X would be: 0.5, 1.5, 4.5
Y would be: 3, 9, 27
When you divide 3 by 0.5 you get six so I basically just did trial and error with all the number
The correct answer for this equation is x^4 + 6x^3 - 12x - 72<span>
You just square root the numbers in the square root sign and take away the square root. Then you simply from top to bottom. Hope this helps :D
