A sector of a circle radius 14 cm subtends an angle 135° at the center of the circle. What is the perimeter of the sector? Take \(\pi = \frac{22}{7}\)

A.

47cm

B.

61cm

C.

88cm

D.

231cm

View answer & explanation

Correct answer is B

Perimeter of the sector = \(2r + \frac{\theta}{360} \times 2\pi r\)

= \(2(14) + \frac{135}{360} \times 2 \times \frac{22}{7} \times 14\)

= \(28 + 33\)

= 61 cm
