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 π = \(\frac{22}{7}\))

A.

14.67cm

B.

73.33 cm

C.

101.33cm

D.

513.33cm

Correct answer is C

Length of the arc = \(\frac{\theta}{360} \times 2\pi r\)

= \(\frac{300}{360} \times 2 \times \frac{22}{7} \times 14\)

= \(\frac{220}{3}\)

= 73.33 cm

Perimeter of the sector = Length of the arc + 2r

= 73.33 + 2(14)

= 101.33 cm
