Exploring Surface Area and Volume of a Sphere

What defines a sphere in geometric terms?

• All points in space at a fixed distance from the center

• A 2D shape with all points equidistant from the center

• A shape with a flat surface

• A cube with six equal sides

What is the relationship between the diameter and radius of a sphere?

• There is no fixed relationship

• Diameter is twice the radius

• Radius is twice the diameter

• Diameter is half the radius
