Answer:
B. Reflect PQR across a horizontal line through R, and then translate the image so R aligns with Z.
Step-by-step explanation:
Imagine a horizontal line through point R. Once you reflect the triangle across this line, it will be facing the same direction as triangle XYZ. Then, once you align R with Z (they are corresponding points!) the triangles will be directly on top of each other.
Answer:
Area of the region = 15.03 in²
Step-by-step explanation:
Area of region between a regular hexagon with sides 6" and circle inscribed.
So Area of region = Area of regular hexagon - area of circle
Now area of regular hexagon = 
where a = side of the hexagon = 6"
Now area of regular hexagon =
= 93.53 square in.
Area of circle inscribed = πr²
Here r is the radius of the circle = 
r = 5"
So area of the inscribed circle = π(5)² = 3.14(25) = 78.5 square in.
Now area of region = 93.53 - 78.5 = 15.03 in²
