Geometry Section 2-5 Part 2

What is a Sphere?

• A round geometric solid, or its surface, with every point on its surface equidistant from its center.

• Symmetrical three-dimensional shape, either solid or hollow, contained by six equal squares.

• A solid geometric figure with straight parallel sides and a circular, or oval, cross section.

What is your Objective?

• Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.

• Know the functions of cones, cylinders, and spheres and use them to solve real-world and methematical problems.

• Develop the topic with relevent, well-chosen facts, definitions, concrete details, quotations, or other information and examples.
