Have you ever thought of the shape of that can? The shape of the can is like a right circular cylinder. There are many examples in our surroundings that have a cylindrical shape. So, In this article, we are going to learn about the meaning and formation of the right circular cylinder, its properties, its surface area &amp; volume, some real-life examples and illustrations.<\/p>\n<h2><strong>RIGHT CIRCULAR CYLINDER<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<h3><strong>MEANING OF RIGHT CIRCULAR CYLINDER<\/strong><\/h3>\n<p>A right circular cylinder is formed by rotating a rectangle about one of its sides as an axis. It is a three-dimensional solid that consists of 2 parallel circular bases that are connected by a closed circular surface in which every base is in the form of a circular disk and each of the circular bases has a similar radius and are parallel to each other. The line passing through the middle of the right circular cylinder is called the axis and the axis of the cylinder conjoins the middle of the 2 circular bases of the cylinder. The perpendicular distance between both the circular bases is called the height of the right circular cylinder, which is represented by \u201ch\u201d in the given figure. The distance from the centre of the circular bases towards its outer boundary is called the radius, which is represented by \u201cr\u201d in the given figure.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/eistudymaterial.s3.amazonaws.com\/rightcircularcylinder1-265x300.jpg\" width=\"300\" height=\"339\" alt=\"\" class=\"wp-image-5069 alignnone size-medium\" srcset=\"https:\/\/eistudymaterial.s3.amazonaws.com\/rightcircularcylinder1-265x300.jpg 265w, https:\/\/eistudymaterial.s3.amazonaws.com\/rightcircularcylinder1.jpg 305w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>&nbsp;<\/p>\n<h2><strong>PROPERTIES OF RIGHT CIRCULAR CYLINDER<\/strong><\/h2>\n<p>1) The line that joins the circular base from the centre is the axis.<\/p>\n<p>2) If a plane cuts the right circular cylinder horizontally parallel to the bases, then the intersection is a circle.<\/p>\n<p>3) To specify a right circular cylinder, we need to know only its radius and its height.<\/p>\n<p>4) The axis forms 90 degrees with circular bases.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>SURFACE AREA OF RIGHT CIRCULAR CYLINDER<\/strong><\/h2>\n<p>The surface space of a right circular cylinder is the total area lined by the surface of it.

When the axis of the cylinder makes a right angle to its circular base, then the cylinder is called a right circular cylinder.<\/p>\n<p><strong>Q2<\/strong>. <strong>What are some real-life examples of cylinders?<\/strong><\/p>\n<p><strong>Ans<\/strong>. Toilet paper rolls, beverage cans, torches etc. are some real-life examples of a cylinder.<\/p>\n<p><strong>Q3<\/strong>. <strong>What is the perimeter of the right circular cylinder?<\/strong><\/p>\n<p><strong>Ans<\/strong>. The lateral or curved surface area of the cylinder is the perimeter of the cylinder. The formula for curved surface area is 2\u03c0rh, where r is the radius of the circular base and h is the height of the cylinder<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>RIGHT CIRCULAR CYLINDER- MEANING, FORMULAE AND ILLUSTRATIONEvery one of you has purchased a beverage can from the shop.
