Question 1 Report

An arc of a circle of radius 14cm subtends angle 300° at the centre. Find the perimeter of the sector formed by the arc (take \( \pi = \frac{22}{7} \))

Answer Details
Perimeter of sector =  ( θ 360 ∘ × 2 π r ) + 2 r
=  ( θ 360 ∘ × 2 × 22 7 × 14 ) + 28
=  ( 5 6 × 2 × 22 7 × 14 ) + 28
= 73.33 + 28 = 101.33cm
