AOB (Major) = 360 - (60+60) = 240°

Length of arc =
[tex] \frac{Angle\: subtended \:by \:arc}{360} \times 2 πr \\ \frac{240}{360} \times 2 \times \frac{22}{7} \times 6 \\ \frac{2}{3} \times 2 \times \frac{22}{7} \times 6 \\ \frac{24 \times22 }{21} \\ = 25.14[/tex]

Answer will be B. 25.13 as this is very close to our answer.
