Question

The given figure is a sector of a circle of radius 10.5cm.
find the perimeter of the sector. (pi=22/7)
Answer it step by step ​

Answer 1

Answer:

11cm

Step-by-step explanation:

perimeter of circle 2πr

perimeter of sector 60/360 × 2πr

$\frac{60}{360} \times 2 \times \frac{22}{7} \times 10.5 \\ = \frac{1}{6} \times 2 \times \frac{22}{7} \times 10.5 \\ = \frac{1}{3} \times \frac{22}{7} \times 10.5 \\ = \frac{22}{7} \times 3.5 \\ = \frac{22}{2} \\ = 11cm$

Answer 2

Answer:

perimeter=angle/360 *2pir

60/360*2*22/7*10.5

1/6*44/7*10.5

11
