First, we need to transform the equation into its standard form (x - h)²=4p(y - k).
Using completing the square method:
y = -14x² - 2x - 2
y = -14(x² + 2x/14) - 2
y = -14(x² + 2x/14 + (2/28)²) -2 + (2/28)²
y = -14(x + 1/14)² - 391/196
-1/14(y + 391/196) = (x + 1/14)²
This is a vertical parabola and its focus <span>(h, k + p) is (-1/14, -391/196 + 1/56) = (-1/14, -775/392).
Or (-0.071,-1.977).</span>

Hello!
You have to find the circumference
You use the equation

r is radius which is half the diameter
This gives us 81.68
Multiply this by 32
81.68 * 32 = 2613.76
This is 217.8133333 feet
The answer is 217.8133 feet
Hope this helps!
