You see, this is correct. Method 1: 3. 14 × 6? - 3. 14×2?
=37.68 - 12.56
=25. 12(cm? )
Method 2: 3. 14×( 6? - 2? )
=3. 14×8
=25. 12(cm? )
And my math book also has a question like this (the first volume of grade six), which is exactly the same as my answer! I just watched it again today and told you!
I told you when I saw the adoption, because I didn't want you to know now, but you may already know. It doesn't matter, I just want to help others, not adopt!
Good luck!
