Please only answer question b​

Answer 1

P = 12 + 2π cm

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 ×
`(60)/(360)`

= 2π × 6 ×
`(1)/(6)`

= 2π

the perimeter (P) = 6 + 6 + 2π = 12 + 2π
