Question

central angle= 120,d= 12.6​

Answer 1

Answer:

Length of the arc of the sector is 13.2 units

Area of the sector is 41.58 square units

Step-by-step explanation:

Given:

Central angle $\theta=120$

diameter = 12.6 units

radius, r=6.3 units

Length of the arc of the sector,

$l=\frac{\theta}{360}*2\pi\:r$

$=\frac{120}{360}*2*\frac{22}{7}*6.3$

$=\frac{1}{3}*2*22*0.9$

$=2*22*0.3$

$\implies\:l=13.2\:units$

Area of the sector

$=\frac{l\:r}{2}$

$=\frac{13.2*6.3}{2}$

$=6.6*6.3$

$=41.58\:square\:units$
