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.

a = 11(4b + c) Multiply/distribute 11 into (4b + c) [multiply 11 to 4b and c]
a = 44b + 11c Subtract 44b on both sides
a - 44b = 11c Divide 11 on both sides to get "c" by itself
You can simplify it to this(but Idk if you have to):
