Today's #geometry problem from May calendar is 1 of a few related problems (I like how this month has several sets that relate to/build on each other)
Tell us how you thought about it; check out whole calendar @ link above.

![The length of the radius of circle O is 4•sqrt2
Four intersecting congruent semicircles form the 4 shaded regions. Find the area inside O and outside all the shaded regions. [The image shows 4 shaded "petals" centered at O and having their tips on the circle]](https://media.mathstodon.xyz/media_attachments/files/114/474/266/411/977/655/original/919e8ce5c48d0d6e.jpeg "The length of the radius of circle O is 4•sqrt2

Reflections and Tangents · Carnival Of MathematicsWelcome to the 239th installment of the Carnival of Mathematics, a roundup of interesting mathematics content from April 2025. The Carnival is a monthly post hosted by a different blog each month. …
Hello #Math folks. I'm trying to remember a problem I thought I saw here recently (but can't find)
Something like this:
A, B prime
P < 300
Find all possible A, B, P such that
A^2 + B^2 = P
Can anyone point me to the post/source? Thanks.
