Too big

huge

I'm not going to crunch the numbers for you but take the area of that triangle and subtract the area of a single circle with a radius of 5 (d of 10)

You forgot the unshaded part of the lower triangle (bottom left)

~19.51 units squared

The area of the triangle is 100, you subtract the area of one of the circles because it takes up exactly one of them (small piece = missing part of big piece) so it's 100 - 25π u^2

Roughly the size of Detroit.

Shade it in.

You can only get an accurate answer with calculus.
Guess you're fucked.

>19.504
->19.50
not 19.51

Oh right this is about 21.46 u^2

But the colored area isn't half of the rectangle. There's a gap at the left side.

This is what I got

i saw a youtube vid on that

go find that

Do the numbers and lines count as "black areas"?

this

shitfuck. I totally didn't notice that. That means that we are missing from 15 upwards on the triangle

wrong. watch closer

21.5 units

100-25(pi)

hello 9gag

nope. too much. look top right

20 * 10 * 0.5 = 100 (area of the triangle)
pi * 5^2 = 78.5 (area of 1 circle)
Subtract Acircle from Atriangle:
100 - 78.5 = 21.5

Still smaller than the amount of nigger cock you've ingested today, OP

fucking W R O N G.
whats your degree??

Look at the bottom left of the lower triangle you will notice its unshaded and is not part of the black area

black areas matter

Here is how you get that bottom left portion.

You should have an idea of how to get the rest of it

Who the fuck cares?

Did you jack that shit from Einsteins portfolio?

did you ever graduate high school?

too long ago, i not remember any of this crap

yes. now show us his calculations for e=mc^2

Einstein plagiarer.

The size of Atlanta

Nah, i wanna do it without integration.

have fun

Damn, I was going to say that.

Einstein didn't invent calculus, retard. Also E=mc^2 is also usually covered in basic high school physics, family.
Doubting you graduated

en.wikipedia.org/wiki/Circular_segment#Area

fpbp

19.50394752017122

90 − 75π / 4 − 25 * arctan(1/2)

I'm guessing that graduating high school means that ones humor is obliterated?

>Divide by half
You mean multiply by half

(200-((pi*25)2))/2=21.46

f=ma

According to Wiki, it's 30 221 532 km²

You just gotta science the shit out of it.

kek

how the fuck are you supposed to know what unit of measurement to use?

>being a snob about school
>doesn't realize it's worthless and you've literally contributed nothing

you kids are so obnoxious and stupid

100 - 25*pi

(20*10-2*(pi*5²))/2 = 21.46...

this is correct

Why would it matter?

You ain't making any conversions so you don't need a unit.

Just use the numbers.

as big as the white one

no

e^(i*pi)

it matters to me

I followed him until he started calculating the sector of the circle.

Good one, the smaller-part-of-the-circle areas are equivalent.

Equivalent to the crime rate

why?

Good one

Done

Ok im an idiot that was the last page

Done actually

2/3

samefag here: because it's not filled

Stop naming your files with that asdf shit you retard.

I can't stand that shit.

t. britfag 18yo nigga

you need to use defined integrals nerd

go bitch somewhere else

>40?????????? more than the whole thing? what is going on

Why do niggas have to mention their a nigga? Are you really that insecure about your race?

dl.dropboxusercontent.com/u/42089158/vid.mp4

actual answer i got was 19.50 i fucked up the calculation

It's not hard to find the size of that not shaded part. Just find the size of the square subtract the circle and take the result and divide by 4.

In a word yes i am, i dislike racism but see it being justified by my own people more than I'm comfortable with.

Good catch

20x10=200 = rectangle
2 cricles = 2+pi+5^2 =round 157,08
so 42.92 should be all the not circle thingies
/2 = 21.46

white thingy left looks like too fiddy to me, so let's say 19

>white thingy left looks like too fiddy to me, so let's say 19
Approximations are not allowed. You have to solve it correctly.

I mean the smaller lower part of it

:^)

Wow, i forgot to divide by two at the last step

Actually the answer is about 19.5046, i forgot to divide by two at the end

if yo divide your 40.96478 by two you get 20.48239. Yes the answer is around 19.504 but i don't see how you came to that conclusion

The rectangle's area is 20x10=200. So the triangle is 100.
Each circle is πr^2 = 25π. There are two, so 50π.
Since the triangle cuts the circles in half, the area of the circles inside the triangle is 25π.
The black area plus that tiny white area to the bottom left is 100-25π.

Now, the problem is that tiny area. We can be really lazy and say "it's a triangle" even if one side is rounded; its base would be 5 and its height would be 5/4 (since each half is proportional to the large triangle); it yields 25/8, making the black area 100-(25π+25/8) = 18.37

okok, i got it boys.
take a quater of rect (10x5=50)
take away half circle (50-39,26=10,73)
div through 2= 5,315

not too fiddy but 5,315
so from last post was 21,46-5,315
black is 15,685

nope

that unshaded part is naughty

Calculate area of rectangle
Calculate area of circles
Subtract area of circles from rectangle
Divide by 8
Multiply by 3
Figure out top right?
Done

oh noes, mistakes were made

Full points for effort though
