GUATEMALA CITY - Torrential rains brought by the first tropical storm of the 2010 season pounded Central America and southern Mexico, triggering deadly landslides. The death toll stood at 15 Sunday but authorities said the number could rise.
Archimedes proved the formula for the area of a circle (A = Ï r 2, where r is the radius of the circle) and showed that the value of Ï lay between 3 + 1/7 (approximately 3.1429) and 3 + 10/71 (approximately 3.1408).
Introduction: A circle is all points equidistant from one point called the center of the circle. Segments drawn near and through the circle create other geometrical objects which we define. The Lesson: We show circle O below.A circle is named based on the name of the point which is the center.The segment OA is a radius of the circle. Definition: A radius is the segment connecting (sometimes referred to as the âdistance betweenâ) the center and the circle itself. In the diagram below, we show circle O with radius OA.ntroduction: A circle is all points equidistant from one point called the center of the circle.
