Answer:
A
Step-by-step explanation:
You should know the area of a circle, A = πr².
So, all you need to find is the area of half a circle, or A = πr²
We see that the radius is half of the diameter or r = 6 in.
A = (3.14)(6)²
A = 56.52 in²
Question 17: B. A’ (1,2), B’ (3,2), C’ (3,5)
Translating 4 to the right means that you should add 4 to the x value of your coordinate point.
Question 18: C. (3,-5)
This is because reflecting over the x-axis would mean to move down the same amount of units above the x-axis the original point is (the original point is five units above the x-axis so you just move down five units). Look at the attached picture for more help.
Question 19: A. C’ (0,-2)
We can see that the triangle has been translated 1 unit to the right and 2 units up. This would mean you add 1 to the x-value of the coordinate and add 2 to the y-value of the coordinate. I can’t see point C clearly, but I’m guessing that it’s at (-1,-4). This would give point C’ as (0,-2)
Hope this helps! Let me know if you need more help! Have a fantastic day!
