Pls helpdjdjdhtv I'm genuinely confused, I've been trying to solve this for like 3 hours (I need two separate answers for each question but you need the 1st question to answer the second one as it states)
if you help I'll literally be so happysiwjejrb

2) 92.1327412287*

3) $288.71**

Step-by-step explanation:

2)Triangle = 1/2(8)11=44

Rectangle =8x3=24

Semicircle = 1/2r²=1/24²=24.1327412287

44+24+24.13=92.1327412287

3) 92.1327412287x3.10=288.711497809

*I don’t know what they want it rounded to.  I used the real pi, but if the directions say to use 3.14 for pi, it would change the answer

**If the first answer changes, so does the second.

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.
