Answer:
20xπ units
Step-by-step explanation:
Use the formula for the length of an arc.
θ/360 × 2πr
The length of the arc and the central angle is already given.
18/360 × 2πr = xπ
Solve for r.
r = (xπ)/(18/360)/(2π)
r = 10x
The radius is 10x.
The circumference is 2πr.
2π(10x)
20xπ
The circumference of the circle is 20xπ units.
Answer:
C. It is used to find the sum of interior angles
Also , it can be used to find the number of triangles in the polygon,
Step-by-step explanation:
Example :
Find the sum of interior angles whose no of sides is 6 and give the name of the polygon
<u>Solution</u>
<u>S = (n-2)180° </u>
S = (6-2)180°
S = (4)180°
S = 720°
The polygon is a Hexagon
