Perimeter why have to +3+3?
Perimeter why have to +3+3?
C is quarter of circle
Quarter is 1/4
Quarter is 1/4
I got it, thank you very much
Answer still 38.97cm. My second answer error.
Why answer back to 38.97? Meaning the small semi circle straight line should not count? Thank you.
See the 3rd picture I answer. Only the red line for perimeter.
Thank you.
