How Do You Find the Surface Area of a Cylinder Using a Net?
Note:
Nets can come in real handy, especially when you're fishing. Nets can be even more useful when you're trying to find the surface area of a three-dimensional solid! Follow along to see how a net can help you find the surface area of a cylinder!
Background Tutorials
-
Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.
-
What is a Rectangle?
A rectangle is one of the many fundamental shapes you'll see in math. Rectangles have special properties that can be very useful in helping you solve a problem. This tutorial introduces you to rectangles and explains their interesting qualities!

-
Represent three-dimensional figures using nets made up of rectangles and triangles, and use the nets to find the surface area of these figures. Apply these techniques in the context of solving real-world and mathematical problems.
-
What is a Solid?
Understanding solids is a building block for finding their lateral area, surface area, and volume. In this tutorial, you'll see examples of solids and learn their different parts. Take a look!
-
What is a Net?
Ever wonder what a box would look like if you unfolded and flatted it? That new picture would be called a net! This tutorial introduces you to nets, a two-dimensional version of a three-dimensional solid. Check it out!

Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle.
-
What is a Circle?
Circles are a fundamental part of math! In this tutorial, you'll be introduced to circles and see the different parts of a circle such as the diameter, radius, and chord. Check out this tutorial to learn about circles!
-
What is Circumference?
The circumference of a circle is the distance around that circle. But what is the formula to find the circumference? In this tutorial, you'll learn the formulas for the circumference of a circle. Take a look!

Know the formulas for the volumes of cones, cylinders, and spheres and use them to solve real-world and mathematical problems.
-
What is a Cylinder?
Soda cans, coffee cans, and some candles are just a few examples of cylinders. In this tutorial, you'll see what defines a cylinder. You'll also see the different parts of a cylinder. Take a look!
