What is a Sphere?
Note:
Every played with a bouncy ball, a volleyball, a basketball, or a baseball? Those are all spheres! Check out this tutorial to see what defines a sphere and learn its different parts. Take a look!
Background Tutorials
-
Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
-
What is a Point?
A point is a fundamental building block of math. Without points, you couldn't make lines, planes, angles, or polygons. That also means that graphing would be impossible. Needless to say, learning about points is very important! That makes this tutorial a must see!
-
What is a Line Segment?
A math term can really tell you a lot about the thing it's describing. Take the term line segment. A line segment is just part of a line! In this tutorial, learn about line segments, how to name them, and what the midpoint of a line segment is!

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!

How Do You Find the Volume of a Sphere?
Want to find the volume of a sphere? If you know the radius of the sphere, you can simply plug that value into the formula for the volume of a sphere and simplify! This tutorial shows you how!
