So i'm new to maths and apparently not very good with it.
I have this two exercises where i have to calculate the area of the blue portions together as the picture below shows.
My strategy for the first one is to calculate the area of the bigger circle, divide it by 2. Then i calculate the area of the smaller circles. In the end i just subtract the smaller ones from the bigger circle. I know i'm getting it wrong because i have the final answers.
As for the second exercise i'm using the same logic but not getting anywhere close to the real answer.
Help, pretty please!
