The answer is
y^2-4x+4y-4=y^2+4y-4x-4=(y+2)²-4x - 8= 0
it is the same of x + 2 = (1/4 ) (y+2)²
the main formula is x-h= a (y-k)² so h=-2, k= - 2 and a=1/4
Answer:
38.25 cm²
Step-by-step explanation:
We use the formula for the length of an arc to find the central angle of the sector of the circle.
Then we use the formula for the area of a sector of a circle to find the area.
Length of arc of circle of radius r:

s = arc length
n = measure of the central angle of the sector



Area of sector of circle of radius r:

A = area of sector of circle
n = measure of the central angle of the sector
