1. Perimeter of Triangles and Rectangles
Without realizing it, we calculate and use the perimeter of triangles and rectangles in regular everyday situations. Learn more about the perimeter of triangles and rectangles in this lesson, and test your knowledge with a quiz.
2. Perimeter of Quadrilaterals and Irregular or Combined Shapes
Sometimes you need to figure out a shape's perimeter whether you have all the information you want or not. In this lesson, you'll learn how to find the perimeter of any quadrilateral as well as more complicated irregular and combined shapes.
3. Area of Triangles and Rectangles
How do you find out the area of rectangles and triangles? Learn how in this lesson! We'll look at the formulas, then practice solving problems for each shape.
4. Area of Complex Figures
Finding the area of shapes isn't always as simple as it is with squares and rectangles. In this lesson, you'll learn how to find the area of complex figures. This includes finding the area of unusual shapes and finding the area of parts of shapes.
5. Circles: Area and Circumference
Understanding how to calculate the area and circumference of circles plays a vital role in some of our everyday functions. They serve as the foundation for operating with three-dimensional figures. Learn more about the area and circumference of circles in this lesson.
6. Volume of Prisms and Pyramids
In this lesson, we'll learn about prisms and pyramids. We'll look at the different types of prisms and pyramids, as well as practice calculating volume for each shape.
7. Volume of Cylinders, Cones, and Spheres
In this lesson, we'll learn about the volume formulas for cylinders, cones and spheres. We'll also practice using the formula in a variety of real-world examples where knowing how to calculate volume is helpful.
8. Finding the Volume of a Triangular Prism
Triangular prisms are objects with triangular bases and rectangular sides. This lesson will explore how you can use the formula for the area of a triangle and the height of the prism to find the total volume of the object.
9. Formula for the Area of an Ellipse
In this lesson, you'll learn some ellipse terminology. You'll also learn the formula for the area of an ellipse and go through a few examples of the equation in action. Then, you can test your new knowledge with a brief quiz.
10. What is Perimeter? - Definition & Formula
In mathematics, the perimeter is the distance around a two-dimensional shape. The formula for finding the perimeter of certain shapes will be discussed in this lesson, and there will be some examples to help you understand how to calculate the perimeter.
11. Surface Area to Volume Ratio
Although it may seem to be just a mathematical activity, the surface-area-to-volume ratio actually has real-world significance. In this lesson, you'll learn how you can calculate this ratio along with how useful this ratio is in various aspects of science.
