Answer:
P = 12 + 2π cm
Step-by-step explanation:
arc length is calculated as
arc = circumference × fraction of circle
the angle subtended at the centre of the sector = 360° - 300° = 60° , then
arc = 2πr × [tex]\frac{60}{360}[/tex]
= 2π × 6 × [tex]\frac{1}{6}[/tex]
= 2π
the perimeter (P) = 6 + 6 + 2π = 12 + 2π
