Learners study the properties of a regular square pyramid and use geometric formulas to find volume and surface area.
Simplifying Algebraic Expressions: Division
By Allen Reed, Douglas Jensen
Learners read definitions of the terminology associated with algebraic operations and then follow steps to use the fundamental laws of division to simplify algebraic expressions.
In this interactive object, learners study the properties of a trapezoid and use a geometric formula to find its perimeter and area.
Ratios and Proportions
In this interactive object, learners simplify ratios and solve problems using proportions. All terms are defined.
By Douglas Jensen
In this animated and interactive object, learners examine the definitions and formulas for radius, diameter, circumference, and area. Students also solve practice problems involving the circumference and area of a circle.
