The answer to your question is:
Step-by-step explanation:
Data
f(x) = -2x² + 8x - 2
Process
-2x² + 8x = y + 2
-2(x² - 4x + 4) = y + 2 - 8
-2(x - 2)² = y - 6
(x - 2)² = 1/2 (y - 6)
Vertex = (2, 6)
Axis of symmetry = x = 2
y-intercept
f(0) = -2(0)² + 8(0) - 2
f(0) = 0 + 0 - 2
f(0) = -2
Domain (-∞, ∞)
Range (-∞, 6]

First find the circumference of the circle.
Circumference:
Plug in 20 for the radius (r).
= 125.66
The circumference of the circle is 125.66 cm.
Now to find this in meters... there are 100 centimeters in 1 meter.
Divide 125.66 by 100 to find how many meters this is.
125.66 ÷ 100 = 1.26
The circle's circumference is 1.26 meters.
