Answer:
The area of the sector (shaded section) is 29.51 .
Step-by-step explanation:
Area of a sector = (θ ÷ 360)
where θ is the central angle of the sector, and r is the radius of the circle.
From the diagram give, diameter of the circle is 26 m. So that;
r =
= = 13 m
θ = 360 - (180 + 160)
= 360 - 340
=
Thus,
area of the given sector = x x
= x x x 169
= 29.5079
The area of the sector (shaded section) is 29.51 .

Answer:
Step-by-step explanation:
Eliminating parentheses, you get ...
-2bx +10 = 16
Subtract 10 and divide by -2b:
x = 6/(-2b)
x = -3/b
__
When b=3, you have ...
x = -3/3
x = -1
