Answer:
96 inches
Step-by-step explanation:
176 divided by 11 equals 16.
This means each square has an area of 16 squared inches.
The square root of 16 is 4. Each side of each square is 4 inches long.
If you count how many sides of the squares line the perimeter, there are 24.
24 times 4 equals 96 inches.
The conic section that the above equation represents is a CIRCLE.
Use completing the square for y and put the equation in standard form:
<span>x</span>²<span>+ y</span>²<span> - 4y + [(-4)/2]</span>²<span> - 1 = 0 + [(-4)/2]</span>²
<span>x</span>²<span> + y</span>²<span> - 4y + (-2)</span>²<span> - 1 = 0 + (-2)</span>²
<span>x</span>²<span> + y</span>²<span> - 4y + 4 - 1 = 4 </span>
<span>x</span>²<span> + (y - 2)</span>²<span> - 1 = 4 </span>
<span>x</span>²<span> + (y - 2)</span>²<span> = 4 + 1
</span>x² + (y -2)² = 5
The radius of the circle is the square root of 5. Its center is found at (0,2)
With this question, you are just going to add up the three numbers
1,300 + 1,400 + 1,500
This equals 2,200
