Answer:
if u divide by 2 1734
Step-by-step explanation:
Please equate 2x^2 -8x -90 to zero: <span>2x^2 -8x -90=0
Next, reduce </span>2x^2 -8x -90=0 by div. all terms by 2: x^2 -4x -45=0
Next, factor the poly: (x-9)(x+5) = 0
Set each factor = to 0 and solve for x:
x-9=0 => x=9
x+5=0 => x= -5
Area of a circle is PI x r^2:
Area of circle = 3.14 x 13^2 = 530.66 square meters.
To find the area of the sector multiply the area of the circle by the fraction of the sector
Area of sector = 530.66 x 150/360 = 221.108 square meters ( Round the answer as needed).
this makes no sense, so imma guess for u.
