Learners study the properties of a right circular cone and use geometric formulas to find volume and surface area.
By Allen Reed, Douglas Jensen
In this interactive object, learners study the properties of a trapezoid and use a geometric formula to find its perimeter and area.
Solving Systems of Linear Equations Using the Substitution Method
In a series of practice problems, learners use the substitution method to solve systems of linear equations, also called "simultaneous linear equations."
