B subtract 18 from both sides
TheThe area of the shaded region if the radius of the outer circle is 4 and the radius of the inner circle is 2 is 12π.
<h3>Area of the shaded region</h3>
Area of a circle = πr²
r =radius of the circle
Area of the outer circle:
Area of the outer circle = π(4)²
Area of the outer circle = 16π
Area of the inner circle:
Area of the inner circle = π (2)²
Area of the inner circle = 4 π
Area of the shaded Region :
Area of the shaded Region = 16π - 4 π
Area of the shaded Region = 12π
Therefore the area of the shaded region if the radius of the outer circle is 4 and the radius of the inner circle is 2 is 12π.

I have done this question yesterday it is 1 and 3
1. 1.5 and 3.5
2. both equations because they share these particular points
Through the slope equation, we know that the slope, or m, is 2.
This gets us to y = 2x + b.
Next we plug in a point and get 4 = 2(3) + b, or b + 6 = 4, or b = -2.
This gives us our answer: y = 2x - 2.
Hope this helps!
