Answer:
The exact length of is 15·π m
Step-by-step explanation:
In the question, we are given;
The radius of the circle with center P, PD, r = 9 m
The measure of m∠APB = 120°
The measure of m∠APC = 60°
The circumference of the circle, C = 2·π·r
∴C = 2 × π × 9 m = 18·π m
= 60°/360° × C = (1/6) × C
∴ = (1/6) × 18·π m = 3·π m
= C -
∴ = 18·π m - 3·π m = 15·π m
= 15·π m ≈ 47.124 m
Therefore, the exact length of = 15·π m
