Answer:
220.5
Step-by-step explanation:
First, we can figure out the half circle. The area for that is pi times r squared divided by 2. So the area is 8 squared times pi divided by 2. So 64 divided by 2 is 32. 32 times pi is 100.530964915. We can round that to 100.5 and now the rectangle is 8 times 15. Which is 120. So 120 plus 100.5 is 220.5! I hope this helps! Please mark me Brainliest!!!

Answer:
7) is not an arithmetic sequence...
9) 
10) 
Step-by-step explanation:
7 is not an arithmetic sequence because consecutive terms of the sequence do not have a constant common difference.
9 has a first term of 0.5 and has a common ratio of 4 (the quotient between the second term and first, then third term and second, etc.). Thus, your equation is 
10 has a first term of -0.25 and has a common ratio of -8 (the quotient between the second term and first, then third term and second, etc.). Thus, your equation is
