Sorry about the drawing but the line starts at the origin of the graph and since it is -x which means it has a negative slope. So the line would start at the origin going down by the slope of -1. hope this makes sense
Answer:
88
Step-by-step explanation:
First find the area of the fountain using the area formula of a circle.
The formula for area is . Here the radius is 5 ft. So the area is
.
We will subtract the area of 78.5 from the larger circle of the brick path and fountain to find only the area of the brick path.
The larger circle has an area of where the radius is 9ft.
Subtract to find the area of the path: 254.34 - 78.5 = 175.84. Divide this area by 2 to find the number of bricks needed since each brick is 2 square feet.
175.84/2 = 87.92 = 88 bricks
