Question

5. Area of a sector is 1/12
th of the circle, then find the measure of central
angle of that arc.​

Answer 1

Answer:

30°(π/6)

Step-by-step explanation:

As Area of a sector is 1/12

th of the circle

∴the measure of central  angle of that arc.=360/12

=30°(π/6)

                              OR

Area of sector(A)=(Θ/360)πr²

1/12πr²=(Θ/360)πr²

1/12=Θ/360

Θ=30°
