........?.............-89
Answer:
false
Step-by-step explanation:
the answer would be false
Let your number be x
your equation will be (x+11)x = -80
expand the equation x^2 +11x +80 = 0
solve the equation and find x
To look for the area of a sector of a circle, the following formula is used:
Area = ( n / 360 ) * pi * r^2
Where: n = measure of arc in degrees
pi = 3.1416
r = radius
Since we are already given all of the needed parts of the formula, direct substitution is done, as shown below:
Area = ( n / 360 <span>) * pi * r^2
</span>Area = ( 45 / 360 ) *3.1416 * (8)^2
Area = 25.133 in^2
Therefore, the area of the sector of the circle is 25.133 sq. in.
0.375 is 3/8 converted into a decimal, to get that you just divide 8 by 3.
