• A shape with one side and four corners

• A shape with four equal sides

• A set of points that forms a square

What is the distance from the center of a circle to any point on its edge called?

• Pi

• Radius

• Circumference

• Diameter

What is the diameter of a circle?

• The total area of the circle

• The distance around the circle

• The distance from one edge to another, passing through the center

• The distance from the center to the edge

What does Pi represent in relation to a circle?

• The ratio of the circumference to the diameter

• The ratio of the radius to the diameter

• The ratio of the area to the radius

• The ratio of the diameter to the circumference

Why is Pi considered an irrational number?

• Because it is a rational number that can be expressed as a fraction

• Because its decimal representation is infinite and non-repeating

• Because it represents the square root of a circle

• Because it can be accurately calculated
