Definition: A circle is the set of all points on a plane that is a fixed distance from the center.
Circumference of a circle is the length around it, also known as the perimeter. Diameter of a circle is the length of the line through the center and touching two points on its edge.
Radius of a circle is the length of the line from the center to any point on its edge. Area of a circle is the number of square units inside of it.
The circumference of a circle can be calculated from its diameter using the formula : Circumference = pie x diameter ( pie = 3.14 ) ( pie = 3.14 )
Example : 18.84 = 3.14 x 6 3.14 6 is the diameter x 6 6 is the diameter x 6 3.14 is pie 18.84 3.14 is pie 18.84
The diameter of a circle can be calculated using the following formula: Diameter = 2 x radius (r)
Example : 20 = 2x 10 (r) 20 is the diameter 20 is the diameter 10 is the radius ( ½ diameter) 10 is the radius ( ½ diameter) 10 10 x 2 x 2 20 20
The radius of a circle can be calculated using the following formula: Radius = diameter / 2
Example: 5 = 10 / 2 10 is the diameter 10 is the diameter ( radius ) 5 is half 10 (diameter) ( radius ) 5 is half 10 (diameter)
r = 6
Diameter Any line segment that passes through the center of the circle and has endpoints on the circle.

Radius, Diameter, and Circumference of a Circle Lesson 7 (3 rd 6 Weeks) TEKS 6.6C.
1.You will explain the definition of a circle, radius, chord, diameter, circumference and arc. 2.You will name and label the terms of a circle. 3.You will.
Circles: Area and Circumference. Definitions Circumference: Distance around the outside of a circle Area: How many squares it takes to cover a circle.
The outside of the circle is called circumference The circumference is the distance around the circle.
