Answer:
∠4 & ∠8
∠3 & ∠7
Step-by-step explanation:
When the transversal (the line that crosses the other 2) intersects through 2 lines, it forms 2 pairs of alternate interior angles.
The alternate interior angles are always located in the inner corners of the intersections and are on opposite ends of the transversal.

It is correct!
Answer:
A = 16pi
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
We are told the circumference is pi8
8pi = 2 * pi*r
Divide each side by 2pi
8pi/2pi = 2pir/2pi
4 =r
Now we want to find the area
A = pi r^2
A = pi(4)^2
A = 16pi
