There are circles all around us in the real world. We can learn a lot about the real world and how it works by understanding circles.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">First, what is the official definition of a circle? <\/h4>\n\n\n\n<p>A circle is a shape that is made up of all the points on a plane (a flat surface) that are the same distance from a given point.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"> What does that mean? <\/h4>\n\n\n\n<p>Okay, so let&#8217;s start out with the &#8220;given point&#8221;. Let&#8217;s pick a point on a flat surface, like this screen, for instance. We&#8217;ll call it point P. <\/p>\n\n\n\n<p>Now pick all the other points on the screen that are the exact same distance R away from point P.<\/p>\n\n\n\n<p> Watch as we add in equal distanced points in the movie below :<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.ducksters.com\/kidsmath\/circle.gif\" alt=\"\"\/><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Wow, we get a circle!<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h4 class=\"wp-block-heading\"> Terms used in circle geometry :<\/h4>\n\n\n\n<h6 class=\"wp-block-heading\"> Radius &#8211; <\/h6>\n\n\n\n<p>The radius is the distance from the center point to the edge of the circle. This is the same distance R we used to make the circle in our definition.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.ducksters.com\/kidsmath\/circle_radius.gif\" alt=\"\"\/><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<h6 class=\"wp-block-heading\"> Diameter &#8211; <\/h6>\n\n\n\n<p>The diameter is a straight line that goes across the circle and through the center. It&#8217;s twice the length of the radius. This gives you our first math equation for the circle:<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.ducksters.com\/kidsmath\/circle_diameter.gif\" alt=\"\"\/><\/figure>\n\n\n\n<h6 class=\"wp-block-heading\"> D = 2 x R <\/h6>\n\n\n\n<p>Also,<\/p>\n\n\n\n<h6 class=\"wp-block-heading\"> R = D\/2<\/h6>\n\n\n\n<p> So the diameter is two times the radius and the radius is one half of the diameter. <\/p>\n\n\n\n<h6 class=\"wp-block-heading\">Circumference &#8211;<\/h6>\n\n\n\n<p> The circumference is the distance around the circle. We use the following formula to figure the circumference: c = d * \u03c0<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.ducksters.com\/kidsmath\/circle_circumference.gif\" alt=\"\"\/><\/figure>\n\n\n\n<p>Uh oh! What is this symbol <strong>\u03c0<\/strong>???<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p> This symbol is called pi. It stands for a number that we use with circles. We won&#8217;t go into the details right now, but let&#8217;s just agree to use it and that it works for now. Okay?<\/p>\n\n\n\n<h6 class=\"wp-block-heading\"> \u03c0 = 3.14\u2026.. <\/h6>\n\n\n\n<p>The decimals actually go on for a long time (forever), but we will round it off to 3.14. It&#8217;s close enough. <\/p>\n\n\n\n<p>Back to circumference; There are a few handy formulas we will use: <\/p>\n\n\n\n<h6 class=\"wp-block-heading\">c = d * \u03c0<\/h6>\n\n\n\n<h6 class=\"wp-block-heading\"> c = 2 * \u03c0 * r<\/h6>\n\n\n\n<p> Where c = circumference, d = diameter, and r = radius. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Other Circle Geometry terms:<\/h2>\n\n\n\n<h5 class=\"wp-block-heading\">Sector &#8211;<\/h5>\n\n\n\n<p> A sector is a section of the circle made by two different radii. Sort of like a piece of pizza or pie.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Chord &#8211;<\/h5>\n\n\n\n<p> A chord is a line segment that joins two points on the circle. The diameter is a special type of chord that goes through the center point of the circle.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.ducksters.com\/kidsmath\/circle_sector_chord.gif\" alt=\"\"\/><\/figure>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Skills needed: Multiplication Basic Geometry A circle is an important shape in geometry.
