I WONDER - What Is The Radius And Diameter?

The video tutorial introduces the concepts of radius and diameter as key measurements in a circle. It explains that the diameter is the longest straight line through a circle, while the radius is half of the diameter. The video concludes with music.

What are the two important measurements in a circle?

• Radius

• Diameter

• Circumference

• Area

How is the diameter defined in relation to a circle?

• It is the shortest line through the circle.

• It is the longest straight line through a circle.

• It is equal to the radius.

• It is a curved line.

What does the term 'diameter' refer to in geometry?

• A line segment that connects two points on the circle.

• The longest straight line through a circle.

• The area of the circle.

• The distance around the circle.

What is the relationship between the radius and the diameter?

• The radius is twice the diameter.

• The diameter is twice the radius.

• They are equal.

• The radius is one-fourth of the diameter.

Explain what the radius of a circle represents.

• The distance from the center to the edge of the circle.

• The distance across the circle through the center.

• The area of the circle.

• The circumference of the circle.
