What is the area of the shaded region?
<u>Formula for circumference of a circle is</u>:
Circumference =
<em>Given circumference of the ring is </em>
<em>Now solving for the radius gives us:</em>
We know that area of a circle is , substituting the value of r we found, we get the area as:
area (A) =
Hence the Area (A), in terms of is
its b cus hit dat hommie
Since we know that the two lines are parallel because of alternate interior angles (5x-20)=3x
then solve for x
5x-20=3x
-20=-2x
x=10°

10y+6
10(5)+6
10*5=50
50+6=56
