Correct Answer: Option D

Explanation

Each interior Angle of the polygon =	(n-2)	180
	_n

=	(6-2)	180
	_6

= 4 x 30
= 120^o
i.e ∠PQR = 120^o ∴ RQD = ¹²⁰/₂ = 60^o also
∴ Δ QOR is equilateral Δ ∴ QO = 7cm
∴ PO = QO = RO ...... = 7cm radius of the circumference of the circle = 2πr
= 2 x ²²/₇ x ⁷/₁
= 44 cm
