There's probably missing something. I think you need some mathematical definitions of the curves / functions.

>>138396632
Nah based on the coordinates you can figure out the curves. Then you can make an equation that adds up the difference

If it was multiple choice that would probably work but if you need an exact answer you would have to do a little work.

ITT angry snow niggers that don't like being told they're stupid

>>138395493
Is that a bad dragon dildo?

quick approximation:

113568 total pixels in the mainsquare.
25846 red pixels

Total area of the main square: 12*12 = 144
Percentage red: 25846/113568 = 0.22758

22.7% of 144 is : 0.22758*144 = 32.77152

Therefore the area of the red zone is approximately 32.77

So this one is pretty easy when you recognize the quarter segments...unless I'm missing it, the other problem was much harder and there was no quarter segment trick. Only brute force answers were found, no clean expression involving pi (29.27625)

I thought we invented computers so that we wouldn't have to deal with this kinda shit anymore.

>>138395493
I think you can solve it with out calculus by thinking of it as four overlapping circles, to which you can take the area of all the circles due to your knowledge of the radius based on the square, then divide the areas by four, due to the overlap only being 1/4 of a circle, eventually just take the difference of each circle and the answer should be really damn precise, even though I'm assuming they're perfect circles.The last thing to do is take in notice of the area (left bottom corner) where both areas overlap, so to correct that, just take the area of the square of both circles( a.- radius=8 and b.- radius=12) divide by four, the difference of circle and square, and add up the shaded areas but subtract your previous answers to get rid of the overlap space getting counted twice.

You start out with the 9x9 grid all white. Then, you fill in figure 1 with red. Fill in figure 2 with white. Fill in figure 3 with red. Fill in figure 4 with red. Fill in figure 5 with white. Each square has length 4, so the area of the red figure is pi*(8^2) - pi*(4^2) + [8^2 - pi*(8^2)] + 4^2 - [12^2 - pi*(12^2)] = pi*128 - 64.

>>138396548
>I mean I know you're just supposed to assume that the curves are circular. But you don't actually KNOW that unless equations are provided.

This.

There must be a note included with this problem stating that all the curves are perfect quarter-circles, otherwise all answers are simply guesses and estimates.

But if there is a note, then the note itself serves as a hint, because then the students know the they must look at the problem in terms of areas of the circles.

Also, their teacher already most likely showed them how to approach such problems as they probably did several examples in class. Students anywhere would be able to do it if they were taught how, if our schools did not pander to black and Mexican kids.
It is doubtful that these Asian kids just came to class one day and the teacher presented them with this problem and expected them to solve it without ever having seen anything similar.

>>138403641

Yeah assuming that they are all perfect quarter circles then the answer is:

from shapely.geometry import Point, Polygon

A = Point(0,12).buffer(12).intersection(Polygon([(0,0), (0,12), (12,12), (12, 0)]))
B = Point(4,12).buffer(8).intersection(Polygon([(4,4), (4,12), (12,12), (12,4)]))
C = Point(8,0).buffer(8).intersection(Polygon([(0,0), (0,8), (8,8), (8, 0)]))
D = Point(8,4).buffer(4).intersection(Polygon([(4,4), (4,8), (8,8), (8, 4)]))

c1 = A.difference(B).difference(Polygon([(0,4), (0,12), (4,12), (4,4)]))
c2 = c1.difference(Polygon([(0,0), (0,8), (8,8), (8, 0)]).difference(C))

THE ONLY FUCKING GOOD METHOD
all these pathetic plebians ITT

We can assume they're all circular arcs. But it's tricky.

First of all, make the graph size 1 rather than 4. Multiply the final answer by 16 at the end to undo this.

To find those areas between two arcs, consider centering the smaller arc at the same center as the larger arc. Then the total area between is

pi (r0^2 - r1^2)

Now consider what happens when we slide the smaller half-circle to the edge (say the right) as shown. The same total area is preserved. But on the left there's more area and on the right there's less. This is easy for the smaller (vertical) pair where one has radius 2 and the other has radius 1. On the bottom the smaller isn't at all, so the area on the bottom is

pi r0^2 / 2

and the area on the top is

pi r0^2 / 2 - pi r1^2 where r0 = 2 and r1 = 1.

Then divide all that by 2 again because you're just looking at the left side, and you get

pi / 2.

It's harder for the two larger circles (horizontal) because when you slide the smaller all the way to the right, there's still some left on the left. Maybe the trig works out easy.

Then how to fix up the lower left corner and avoid double counting it.

>>138396425
>>138395493
It takes 2 pieces of knowledge, finding area of a circle based on radius length, and common addition subtraction. That's it.

>>138398664
More or less what I did, but dealing with the lower left corner still requires attention.

>>138408257
What the fuck... either use a smart trick like >>138398664 or don't fuck around and set theory it in place like >>138404076

>>138408418
Also need the square root of 2 to help with the truncated bits. But yeah pretty much just that.

>>138408630
The "smart trick" doesn't solve the problem in the lower left. It's just a visual of what I calculated.

And the "set theory" is code that gives a numerical answer, what should be wanted is something with integers and pi.

>>138408840
You cannot express it just in integers and pi, you also need square root of 2.
