<p>To find the number of sides of a regular polygon inscribed in a circle, where a side subtends an angle of 30 degrees at the center, we can follow these steps:</p><p><strong>Step 1: Understand the relationship between the angle and the number of sides<
Identify the center, a radius, an apothem, and a central angle of polygon. Then find the measure of a central angle. 相关知识点: 试题来源: 解析 Sample answer: center: point L, radius: (LK), apothem: (LM), central angle: ∠ ALK, 36° 反馈 收藏 ...
What is the diagonal of a polygon? What are the properties of regular polygons? Is a circle a polygon? What is the minimum number of sides a polygon must-have? Can a number of angles and the number of sides for a polygon be different?
A cone is a polyhedron. True False True or False: 1. If a ray bisects an angle of a triangle, then it also bisects the side opposite the angle. 2. If a plane intersects a cylinder, then the intersection must be a circle.
Since the wire is bent into a regular polygon with n sides, the length of each side l can be calculated as: l=2πrn 2. Identify the Geometry: The polygon can be inscribed in a circle of radius r. The angle subtended by each side at the center of the polygon is: θ=2πn...
Regular pentagon DEFGH has a center C, apothem BC, and central angle DCE. To find the area of a regular n-gon with side length s and apothem a, divide it into n congruent isosceles triangles. area of each triangle: total area of the polygon: The perimeter is P = ns. ...
(US 20139-10, Question #27) A regular 13-sided polygon is inscribed in a circle with center O. Triangles can be formed by choosing three vertices of this polygon to be the vertices of the triangle. How many of the triangles that can be formed in this way contain the point O?( ) A...
The polygon circumscribes a circle. What is the perimeter of the polygon? What are the different kinds of polygons? What is the relationship between the number of sides, angles, and vertices in a polygon? What is the sum of the angle measures of a polygon with 37 sides?
No matter how large or small a circle is, pi will always work out to be the same number. Pi (π) is the 16th letter of the Greek alphabet and is used to represent the widely known mathematical constant. Who invented pi? Pi has been known for nearly 4,000 years and was discovered ...
