Solid geometry word problems (practice) | Khan Academy
Solve problems concerning real-world situations with the volumes of cones, cylinders, and spheres.
Solid geometry - Khan Academy
Welcome to our fun Solid Geometry unit! We'll explore the cool world of 3D shapes and how they're different from 2D ones. Learn about Cavalieri's Principle and how to cut shapes into pieces. Discover how to measure volume and surface area, and even find out how heavy things are with density! Get ready for a 3D adventure!

Get ready for circles and solid geometry | Khan Academy
In this unit, we're circling back to one of the most fundamental shapes in geometry: the circle! We'll talk radius, diameter, circumference, and area, and even take a bite out of "pie" to get a full understanding.
Shapes | Geometry (all content) | Math | Khan Academy
Classify shapes and solve problems using what we know of the properties of shapes.

Unit 15: Analytic geometry - Math | Khan Academy
About this unit. In analytic geometry, also known as coordinate geometry, we think about geometric objects on the coordinate plane. For example, we can see that opposite sides of a parallelogram are parallel by writing a linear equation for …
Geometry - Khan Academy
In this topic, we'll learn about special angles, such as angles between intersecting lines and triangle angles. Next, we'll learn about the Pythagorean theorem. Finally, we'll find volume of curved 3D shapes like spheres, cones, and cylinders.
