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.

Answer:
1. 109
2. 29
3. 71
Step-by-step explanation:
1. since a triangle's interior angles always add up to 180, you can add 35 and 36 to get 71, then subtract that from 180 to find the third angle
2. the unnamed angle in triangle RUV is supplementary to <1.Supplementary angles are angle the add up to 180. So you can subtract 109 from 180 to find the unnamed angle. It is 71. Now you can repeat the steps in question one to find <2 in triangle RUV. You get that <2 is 29
3. Angle 3 and the unnamed angle are vertical angles. This means that they are opposite to each other and are congruent. This means that they have the same measure. Knowing that the unnamed angle is 71, we can say that angle 3 is also 71.
Answer:
Step-by-step explanation:
The midpoint of two coordinates (x1, y1) and (x2, y2) is expressed as;
M(X,Y) = {(x1+x2)/2, (y1+y2)/2}
Given the points A(h, k) and B(h,j)
x1 = h, y1 = k, x2 = h, y2 = j
Substitute into the formula;
M(X,Y) = {(x1+x2)/2, (y1+y2)/2}
M(X,Y) = {(h+h/2, (k+j)/2}
M(X,Y) = {(2h)/2, (k+j)/2}
M(X,Y) = {h, k+j/2}
hence the coordinates of point M is {h, k+j/2}
Answer:
<h2>
the associative property</h2>
Step-by-step explanation:
the associative property, the order of the numbers does not change their product
3 * 8 = 8 * 3
24 = 24
