Answer:
The length of the border is approximately 4 feet.
Step-by-step explanation:
Since the garden has a circular border we can apply the formula for the circle's length, which is shown below:

Where the radius is half the diameter. The diameter is the distance between two points in the circle going through the center, therefore for this garden the diameter is 1.2 feet and the radius is 0.6 feet. Applying this to the formula gives us:

The length of the border is approximately 4 feet.
Answer:
Plug in the X value given on the side. The first one should be 14. That means your ordered pair is -2,14. Once you've got all the values, plug all the ordered pairs into the graph.
The area of a circle is given by:

Where r is the circle's radius. In this case we have a diameter of 8cm so the radius 4cm. Using pi=3.14 we have that the area of the circle is:

So the area is 50.24 cm^2.
The answers to a system of equations are the intersections, because those are the points where the two sides are actually equal. In this case, the line and parabola intersect at (4,0) and (9,5)
