Hello!
3,486 / 2 = n
n = 1743
work:
you simply divide 3,486 by 2
if you divide each number by two (right to left)
6 / 2 = 3
8 / 2 = 4
4 / 2 = 2
3 / 2 = 1.5
since there is a decimal in this, multiply it by 10 and add it to the number before. this number will go on the right side of the total
1.5 * 10 =15
15 + 2 = 17
17 4 3 are the final numbers in order. put them together and you have 1743

<u>(this is my personal way of doing it, but there are plenty more ways to do it)</u>
I hope this helps, and have a nice day!
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.
