Peter drew a regular hexagon, the vertices of which lay on a circle 16 cm long. Then, for each vertex of this hexagon, he drew a circle centered on that vertex that ran through its two adjacent vertices. The unit was created as in the picture. Find the ci - Length of the arc
What is the arc length of a circle k (S, r=68mm), which belongs to a central angle of 78°?
- Arc
The length of the circle is 18, and the arc length of the circle is 1. What is the magnitude of the angle of this arc? - The circle arc
