In the diagram, ∠POQ = 150 and the radius of the circle PSQR is 4.2cm. [take π = 22/7]
What is the length of the minor arc?
Attached Figure / Diagram
A
11cm
B
15.4cm
C
17.64cm
D
23.10cm
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
\(\frac{θ}{360}\) * 2 * π * r → \(\frac{150 * 2 * 22 * 4.2}{360 x 7}\)
= 11cm
