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

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

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.

why was that problem more interesting then math class

:thinking:
