I Introduction and purpose of task: The purpose of this task is to investigate the positions of points in intersecting circles and to discover the various relationships between said circles. Circle C1 has center O and radius r. Circle C2 has center P and radius OP. Let A be one of the points of intersection of C1 and C2. Circle C3 has center A and radius r (therefore circles C1 and C3 are the same size). The point P’ (written P prime) is the intersection of C3 with OP. This is shown in the diagram

Arc Length The definition of radian measure s = rθ The unit circle An angle of 1 radian Proof of the theorem IT IS CONVENTIONAL to let the letter s symbolize the length of an arc‚ which is called arc length. We say in geometry that an arc "subtends" an angle θ; literally‚ "stretches under." Now the circumference of a circle is an arc length. And the ratio of the circumference to the diameter is the basis of radian measure. That ratio is the definition of π. π | = | C D | . |

Program To play connect four‚ you have a standing-up board with seven vertical rows of clear circles‚ and six horizontal rows of circles‚ making up a total of forty-two circles. You will also need two players‚ or a single person that will play as both. First‚ player one puts a red circle piece into one of the seven columns‚ and then player two puts a blue circle piece into one of the seven columns. The circle pieces will go to the lowest vacant spot on the vertical row it was selected on. You keep repeating

Fundamental of Islamic Ornament in Geometrical Art Abstract Islamic ornament is underlying the pictorial or an icon. It ’s inspirational is from nature like stars‚ moon‚ trees and etc. Islam stricly does not allow arts in form of living things such as human and animal. In order to inhibit worshipping idol other than worshipping Allah subahanahuwataala. Basically the art of Islam can define as merge of science and mathematics learnings. In this content we will be more focing on geometry

A cylinder is a shape with a circular bottom at the both ends that kind of looks like a pringles potato chip bottle THE formula of finding the volume of a cylinder is base area times height of cylinder. The base area will be the area of the circle which is pi x radius x radius So you just take that answer and multiply it by the height of a cylinder. done math math math cylinder cylinder asdfghjk lkjhgh jhgf ghjxskdskdgc kdshfkhshfkshksskkkkjs wordlimit mine is
