Sometimes, you might be given a sphere\u2019s diameter in a math problem. Remember &#8211; the diameter of a sphere is twice the distance of the radius. That means you can divide the length of the diameter in half to find out the radius.&nbsp;<\/p>\n\n\n\n<p>For example, let\u2019s say we wanted to find the total volume of a spherical chocolate candy with a radius of 2cm \u2014 this is how we\u2019d use the volume formula:<\/p>\n\n\n\n<p><strong>V = 4\/3 \u03c0r<sup>3<\/sup><\/strong><\/p>\n\n\n\n<p>V = 4\/3 (\u03c0 x 2)<sup>3<\/sup><\/p>\n\n\n\n<p>Final answer = V = 33.51cm<sup>3<\/sup><\/p>\n\n\n\n<p>You can also use a sphere calculator like<a href=\"https:\/\/www.google.com\/search?q=sphere+calculator&amp;ei=E-MHZLjaA43U4-EPsuy7mAQ&amp;ved=0ahUKEwj4r4bFlcv9AhUN6jgGHTL2DkMQ4dUDCBA&amp;uact=5&amp;oq=sphere+calculator&amp;gs_lcp=Cgxnd3Mtd2l6LXNlcnAQAzIFCAAQgAQyBQgAEIAEMgUIABCABDIFCAAQgAQyBQgAEIAEMgUIABCABDIFCAAQgAQyBQgAEIAEMgUIABCABDIFCAAQhgM6DAgAEOoCELQCEEMYAToTCAAQjwEQ6gIQtAIQjAMQ5QIYAjoTCC4QjwEQ6gIQtAIQjAMQ5QIYAjoECAAQQzoFCAAQkQI6CwguEIAEEMcBENEDOgsIABCABBCxAxCDAToKCAAQsQMQgwEQQzoICC4QsQMQgAQ6CwguEK8BEMcBEIAEOgsILhCABBDHARCvAToHCAAQgAQQCkoECEEYAFAAWOIXYOcYaAFwAXgBgAH1AogB2RqSAQgwLjEwLjQuMpgBAKABAbABFMABAdoBBAgBGAfaAQYIAhABGAo&amp;sclient=gws-wiz-serp\"> this one<\/a>.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">How to find the surface area of a sphere<\/h5>\n\n\n\n<p>To find the surface area of the sphere, we will use the formula&nbsp; <strong>SA = 4\u03c0r<sup>2<\/sup><\/strong>. We\u2019ll also go back to the chocolate candy example we used to find the volume, where the radius was 2cm.&nbsp; Here is how solving for the surface area would work with the formula:<\/p>\n\n\n\n<p><strong>SA = 4\u03c0r<sup>2<\/sup><\/strong><\/p>\n\n\n\n<p>SA = 4 x(\u03c0 x 2)<sup>2<\/sup><\/p>\n\n\n\n<p>Final answer = SA = 50.27cm<sup>2<\/sup><\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Real-life applications for volume of a sphere<\/h5>\n\n\n\n<p>Knowing how to calculate the volume of a sphere is important, and not just for success inside a mathematics classroom. Volume of a sphere has many real life applications that are spread across a wide range of areas.<\/p>\n\n\n\n<p>In cooking, understanding the volume of a sphere as well as a generic base of knowledge for spatial relations helps when preparing round-shaped dishes, such as cakes, cookies, meatballs, etc. It also aids in the measurement of ingredients for food preparation.&nbsp;&nbsp;<\/p>\n\n\n\n<p>When designing submarines, ships, and other watercraft items, knowing how to calculate the volume of a sphere helps with determining the buoyancy of the items. This is a critical component of physics and engineering with sound design.<\/p>\n\n\n\n<p>For packaging and manufacturing, designers use the calculations from determining the volume of a sphere to assist in knowing the size and capacity for various containers to efficiently and attractively pack up and display spherically shaped objects such as ball bearings, sports balls, medicine capsules, etc.<\/p>\n\n\n\n<p>These are just a few of the many real-life applications that are affected by knowing how to calculate the volume of a sphere.
