Nah, you’d have to make assumptions, like the fact that it’s actually a semi-circle, which isn’t provided.


#11202

BD would also equal AE right


#11203

Oh, right. I should say that.

ABED is within a semicircle.


#11204

sorry, inexact wording is a scourge on fools who try to set maths questions on online forums


#11205

wouldn’t the square area be 50 unless I totally forgot the forumula for how to get the area of a square

Yes ik it isn’t the forumula for that shaded thing just wondering


#11206

Squares are rectangles, but rectangles aren’t necessarily squares.


#11207

still would be right tho


#11208

AH I wish I knew the radius of this thing


#11209

updated including stress-inducing amount of marks, triggering PTSD flashbacks to maths tests


#11210

I have to go now lmao


#11211

this is bothering me I want to figure it out


#11212

You can get the radius by making it a full circle and square and then finding the distance from B’ to B with Pythagoras.


#11213

the circle to square step is unnececary


#11214

*semicircle to circle step

You can figure it out pretty simply with the fact that C is the midpoint


#11215

After getting the whole area of the circle you can subtract the area of the square from it and divide it by 4. Should be it.


#11216

Then we can get the area of the whole circle and divide it by 2 and minus it by the square area to get all those 3 spaces area and then Idk

I think the above is possible


#11217

or that


#11218

yeah that is correct
although uhhh in the original version of the problem we used more difficult lengths


#11219

I can’t believe you somehow made me do geometry again.


#11220

why was that problem more interesting then math class

:thinking:
