Question

What is the area?

Answer 1

SO do you know the formula of this shape, which is trapeziod?

Answer 2

Nope i so confused with it .

Answer 3

\(\bf \textit{area of a trapezoid}=\cfrac{h}{2}(base1\cdot base2)\)

Answer 4

Okay the formula is \[A=\frac{ a+b }{ 2 }h\]

Answer 5

I got no idea what that means or where to start..

Answer 6

hmmm actaully that's .. right so... should be rather \(\large \bf \textit{area of a trapezoid}=\cfrac{h}{2}(base1 + base2)\)

Answer 7

start off by getting the bases

Answer 8

...?

Answer 9

So mostly you have A= base 1 and B= Base two. Which two bases are in the trapezoid.

Answer 10

Look at the trapezoid.

Answer 11

i know 1 witch is 6in

Answer 12

Yes one of the bases is 6in now find the other base.

Answer 13

\[A=\frac{ 6+b }{ 2 }h\]

Answer 14

8?

Answer 15

Yes

Answer 16

\[A=\frac{ 6+8 }{ 2 }h\] Now what is the height.

Answer 17

7????????

Answer 18

No, it is on the trapeziod you dont need to do any math yet.

Answer 19

oh im confused again

Answer 21

Look at that real quick.

Answer 22

What is 10in?

Answer 23

highth?

Answer 24

yes so on the formula that would be h.
So now the formula would be:
\[A=\frac{ 6+8 }{ 2 }10\]

Answer 25

So now you solve that.
What is 8+6?

Answer 26

14

Answer 27

14 divide by 2

Answer 28

7

Answer 29

Multiply that by the height. What would be your answer

Answer 30

so the area is 70?

Answer 31

yes, would be the answer

Answer 32

Do you need any other help.

Answer 33

Yes one more if you dont mind.

Answer 34

sure

Answer 35

I can help you with the other question.

Answer 36

What is the approximate perimeter of the figure?

Answer 37

?

Answer 41

hint: the distance around those curved edges will be equal to

\[\Large \frac{\pi*r}{2}\]

where r is the radius of the circle

Answer 42

.? i need more explaining..

Answer 43

the symbol \(\Large \pi\) is pi, approximately the number 3.14

Answer 44

oh wait I made a typo

Answer 45

R stands for radius

Answer 46

it should be \[\Large \frac{2*\pi*r}{2} = \pi*r\]

Answer 47

anyways, if you had a radius of say 10, then the distance around the curve would be approximately pi*r = 3.14*10 = 31.4

Answer 48

how do i find r?
