Learn to define the radius of a circle. Learn what the radius formula is and how to find the radius of a circle given area, diameter, or...
Half of a circle’s area is the area of the semicircle. Discussion with Illustrative Examples Example 1:The relationship between the radius and diameter of a semicircle. In a semicircle, the diameter is twice the radius’s length, connecting two points on the circle and going through the cent...
We consider the following geometric optimization problem: find a maximum-area rectangle and a maximum-perimeter rectangle contained in a given convex polygon with n vertices. We give exact algorithms that solve these problems in time O(n3). We also give (1−ε)-approximation algorithms that tak...
