The middle semi-circle is annyoing
hearty cairn
Split the shape into multiple shapes, one triangle with length 5 and height 10
clever minnow
Do 2.5 squared + 25 - 1.25 squared

Ye good method
hearty cairn
And the semicircle can be calculated by halfing the circle formula, then using that on both shaded and unshaded
clever minnow
Do 2.5 squared + 25 - 1.25 squared
Ye pretty much half this
hearty cairn
Shaded semi circle - unshaded

Hey @hearty cairn is ur problem solved ?

Solution
- Find triangle area = 1/2 * (base = 5) * 10 (height)
- Find Semicircle area (big one)[pi * 5 * 5 * 1/2] and substract it from the small one[pi * 2.5 * 2.5 * 1/2].
- Add them up.
