Answer:
8
Step-by-step explanation:
I believe that the answer is 8
The area of the composite figure can be calculate
120 pi x 5.1 1922.6547
1922.6547 divided by 7.4 =259.8182
259.8182 + 3.2 = 263.0182
Using two point form
y-5/-4-5=x-10/13-10
rearrange to get 3x+y-35=0
The answer is the last choice. (a, b), in this question, means the domain or range is from a to b, exclusive. When you use ∞, you would always use the exclusive.
