Introduction to Circles

A circle is a set of ​ (a)   that are ​ (b)   distance from a ​ (c)   point.

• points
• equal
• center
• lines
• opposite
• double
• middle

The center is also called the ​ (a)   of the circle.

• origin
• middle
• circumference
• radius
• diameter

The ​ (a)   is the distance from the center of a circle to any other point on the perimeter of that circle.

• radius
• diameter
• circumference
• origin
• center

What is the diameter of a circle?

• The total length around the edge of the circle.

• The distance from the center of any circular object to its outermost boundary.

• The distance from one side of a circle to the other side, passing through the center.

• The ratio of a circle's circumference to its diameter.

The diameter is the same as ​TWO ​ (a)   lines drawn in exactly ​ (b)   directions.

• radius
• opposite
• parallel
• curved
• the same
• intersecting

What is the perimeter of a circle called?

• Area

• Radius

• Diameter

• Circumference

Pi is the ​ (a)   of the distance ​ (b)   a circle to the distance ​ (c)   a circle.

• ratio
• around
• across
• different
• opposite
• number
