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.

Answer:
0.611 rad
Step-by-step explanation:
For the radian measure:
180° = π radians
180° : 110° = 11 / 18 ≈ 0.611
110° = 11π/18 rad ≈ 0.611 rad
5/2=2.5 So you can write this as a fraction. 2 5/10 and then simplify 2 1/2. I hope this helps. :) Brainliest answer please. :)
Answer:
If both statements are true or if both statements are false then the converse is true. A conditional and its converse do not mean the same thing.
Step-by-step explanation:
Step-by-step explanation:
Equation of straight line: y=mx+b
Given slope=2, hence m=2
y=2x+b
Replace y and x values as stated in the question (-1, -2)
(-2)=2(-1)+b
-2+2=b
b=0
rewrite the equation:
y=2x+0
y=2x
For 3) a solid line is used when the equation is <= or => while dotted line is for when the equation is < or >
Could you elaborate on question 2? I dont quite get what the question is asking for
