The answer is 8, that line is 180° and we know 140. 180-140=40 and it’s 5x so that leaves us with 5x=40. divide 5 on both sides leaving 8
Answer:
Circumference of a circle
Area of a sector of a circle is (Angle of Sector/360°)*πr^2
If you plug in the given values, you get (30°/360°)*36π
Simplify the equation.
(1/12)*36π
Simplify the equation again and you get your answer.
Area = 3π

Step-by-step explanation:
Correct option is B)
The circumference of the circle is 96 units.
Therefore, 2π×r=96
⇒r=
2×22
96×7
=15.27 units
Now, in the quadrilateral OLMN,∠OLM+∠LMN+∠MNO+∠NOL=360
o
Given that LM and MN are tangents to the circle, ∠OLM=∠ONM=90
o
∴∠NOL=360−90−90−60=120
o
The length of arc is given by rθ where θ is the angle made by the arc at the centre in radian.
Thus, arc length LN=15.27×
180
120π
=31.98
