Question

OPQ is the sector with centre 0 and radius 15 cm . Measure angle pOQ is 30' ..find the area enclosed by arc PQ and chord PQ​

Answer 1

Given Data :

Radius = 4 cm

Angle subtended at the centre ‘O’ = 30°

Formula to be used :

Length of arc=θ360∗2πrcm

Length Of Arc=30360∗2π∗4cm

= 2π3cm

Therefore, the Length of arc the length of the arc that subtends an angle of 60 degrees is 2π3cm
