It is formed when a line passes through the center and touches the two ends of the circle. This line is called the diameter of the circle.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full eplus-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"620\" height=\"404\" src=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/01\/a-circle-showing-center-radius-and-diameter.png\" alt=\"A circle showing center, radius, and diameter\" class=\"wp-image-37351\" title=\"A circle showing center, radius, and diameter\" srcset=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/01\/a-circle-showing-center-radius-and-diameter.png 620w, https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/01\/a-circle-showing-center-radius-and-diameter-300x195.png 300w\" sizes=\"auto, (max-width: 620px) 100vw, 620px\" \/><\/figure>\n\n\n\n<p class=\"eplus-wrapper\">In the figure above, you can see the diameter dividing the circle into two halves.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper\">You can also see a blue line drawn from the circle&#8217;s center to a point on its edge. The length of the line gives the radius of the circle.<\/p>\n\n\n\n<p class=\"eplus-wrapper\">All points on a circle are at an equal distance from its center. So, no matter which point you touch from the center, the radius will always be the same.<\/p>\n\n\n\n<div id=\"recommended-games-container-id\" class=\"recommended-games-container\"><h4

perimeter or circumference describes the total length of the boundary of the semicircle.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper\">You may think that the perimeter of a semicircle is half the perimeter of a circle, but that is not true.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper\">Half the perimeter of a circle gives the perimeter of the curved part only. You will also have to add the diameter line across the bottom to get the total perimeter.<\/p>\n\n\n\n<p class=\"eplus-wrapper\">Recall that the perimeter of a circle is 2<em>\u03c0r<\/em>.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper\">So, the perimeter of the curved part of the semicircle is \u00bd \u00d7 2<em>\u03c0r<\/em> = <em>\u03c0r<\/em><\/p>\n\n\n\n<p class=\"eplus-wrapper\">Now, let&#8217;s add the length of the diameter as well.<\/p>\n\n\n\n<p class=\"eplus-wrapper\">So, the total perimeter of the semicircle = <em>\u03c0r<\/em> + <em>d<\/em>, where <em>d<\/em> is the diameter.<\/p>\n\n\n\n<p class=\"eplus-wrapper\">But, we also know that the diameter of a circle is twice its radius.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper\">So, substituting the diameter with the radius in the above equation, we get,<\/p>\n\n\n\n<p class=\"eplus-wrapper\">The perimeter of semicircle = <em>\u03c0r<\/em> + 2<em>r<\/em><\/p>\n\n\n\n<p class=\"eplus-wrapper\">Or, perimeter = <em>r<\/em> (<em>\u03c0<\/em> + 2)<\/p>\n\n\n\n<h2 class=\"wp-block-heading eplus-wrapper\" id=\"3-solved-examples\">Solved Examples<\/h2>\n\n\n\n<p class=\"eplus-wrapper\"><strong>Example 1: A circle has a diameter of 14 cm.
