Hello :)

So, the diameter² would be: 2²+2²=8
radius²=4
area of the full circle = 4pi
area circle - area square = 4pi - 4 = 4(pi-1)
since it's only 2 parts, the pink area would be:
2(pi-1)

If I didn't miss something :3
Anyway, thanks for the opportunity :)

Area of square =2x2=4
Area of half square =2
Diameter of circle is calculated from hypothesis formula.
So we got radius. And area of semicircle.
Hence area of pink parts = area of semicircle - area of semisquare = pie - 2=3.14-2=1.14 square units.
And followed. Follow me too.

Sorry man thats not the answer... if youre using pythag then it would = root 8 not 8

i put "diameter² = 8" , not diameter=8 :p
but yeah, in fact i didn"t know the name for root in english xD sorry^^
the problem in my logic is that:
radius² = 2 and not 4, since you divide by 2² and not only by 2, my bad :)
so the answer is:
area full circle = 2pi
2pi - 4 for the area circle-area square
pi -2 is the answer :D

(btw, if i couldn't post two answers, I can delete my com if you want :))

~= 10.58

1.145

You forgot to devide the diameter by 2 to get the radius

May I suggest you add tags such as #mathematics or #math as very little is published under #maths alone. You will also get more exposure in the Mathematics forum by using one of those tags first.
