1.09 because all percents are divided by 100 to find the decimal
Hey there Panda!
Question #1
(3.5*3.14 = 10.99 rounded would be 11) 11 is your answer.
Question #2
The circumference equals 21.99, but rounding it would be 22.00
Question #3
We divide 12/2 and from this we get 6. We doing (6*3.14) and then multiply by 2 and then divide by it's circumference and then we get it area. The answer that I got was 452.39, but from looking at your options, your correct answer would be 452.2 (ft)
Question #4
So, by looking at this weird shape, we see that the integer's are 8 by 5. When doing area, we often multiply. As we do this with these number's, we get 40.
We do 8/4 = 2; 5/2 = 2.5. So, from doing this, we get 90.2 (ft).
Question #5
With this last question, I believe that the answer may be C.) So, what I did was I did the radius x's 3.14 and got 6.28 then minus 10 and got around 3.
Hope this helps.

For a, x = 6 (3+6=9) and for b, y=5 (2x5=10)
Answer:
answer b
Step-by-step explanation:
Answer:
x = -5 ±4sqrt(3)
Step-by-step explanation:
(x + 5)^2 = 48
Take the square root of each side
sqrt((x + 5)^2) = ±sqrt(48)
x+5 = ±sqrt(16*3)
x+5 = ±4sqrt(3)
Subtract 5 from each side
x = -5 ±4sqrt(3)
