GA - Geometric Applications Module Overview
Geometric Applications Module Overview
Introduction
Students will learn to use the formulas for area and circumference of a circle to solve problems. They will explain the relationship between the circumference and area of the circle. Students will learn to solve real-world problems that involve area, volume, and surface area of two and three dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.
Essential Questions
- How do you find the circumference of a circle?
- How do you find the area of a circle?
- How can you use the circumference of a circle to find the area?
- How are circumference and area of circles related?
- What is a composite figure?
- How can you find the area of a composite figure?
- How can you find the volume of a figure composed of cubes and prisms?
- How can you find the surface area of a figure made up of prisms?
Key Terms
The following key terms will help you understand the content in this module.
Area - Area is the number of square units necessary to cover a given surface.
Diameter - The diameter of a circle is a line segment that passes through the center of a circle and whose endpoints lie on the circle.
Circumference - The circumference is the distance around a circle and is found by multiplying the diameter by 3.14(pi).
Composite Figure - A composite figure is a shape that can be divided into more than one of the basic figures.
Pi - Pi is the ratio of a circle's circumference to its diameter. The constant represented by 3.14.
Radius -The radius is a line segment that represents the distance from the center of a circle to a point on the circle.
