An arc of a circle of radius 14cm subtends angle 300o at the center. Find the perimeter of the sector formed by the arc
-
A.
14.67cm -
B.
42.67cm -
C.
101.33cm -
D.
543.33cm
Correct Answer: Option C
Explanation
The perimeter of the sector (=2r+frac{theta}{360}times 2pi r \
Rightarrow 28 + frac{300}{360} times frac{2}{1} times frac{22}{7}times frac{14}{1} = frac{220}{3}+28\
73.133+28=101.33cm)
