Answer:
20,939.00 ft²
Step-by-step explanation:
To solve this you first need to find the radius of the circle.
Circumference (C) = (2)radius (r)
163.28=2r
163.28/2=2r/2
81.64=r
Area of a circle (A) = πr²
A=π(81.64)²
A=π(6665.0896)
A=20938.99652
This can be simplified to 20,939.00 ft²
3.25 - 3 = 0.25
3 - 2.75 = 0.25
2.75 - 2.5 = 0.25
2.5 - 2.25 = 0.25
Since we subtracted those numbers, it means we are decreasing.
Therefore, the answer is decrease by 0.25.

Answer:
y = 5 -x
6x +3(5 -x) = 27
Step-by-step explanation:
The first equation is conveniently solved for either x or y. If we solve it for y, we get ...
y = 5 - x . . . . . . subtract x from both sides
This expression for y can be substituted into the second equation to give ...
6x +3(5 -x) = 27
These are your new system of equations.
Simplified, they are ...
_____
The second is a 2-step equation that gives the value of x, which can then be used in the first equation to find y.
3x = 12 . . . . subtract 15
x = 4 . . . . . . divide by 3
y = 5 -4 = 1 . . . . substitute into the first equation
The solution is (x, y) = (4, 1).
