IT is given that ∠APC = 92 and PB = 8 in. The arc length of AD is ≈ 3.67π in.
Arc length is defined as the distance between two points along a section of a curve.
IT is given that
∠APC = 92 and PB = 8 in
As ∠APC and ∠APD are formed in linear pairs.
So,
∠APC + ∠APD = 180∘
∠APD = 180 - ∠APC
∠APD = 180∘ − 92∘
∠APD = 88∘
Now, the length of the arc will be,
= Ф/360 2πr
= 88/360 x 2 x π x 8
=88/360 x 16π
=352/90 x π
≈ 3.91π in.
Hence, the arc length of AD is ≈ 3.91π in.
