Please understand the following:
Center point of circle is the name of the circle.
Radius is the distance from the center of the circle to a point on the circle - it is a line segment.
The plural of radius is radii.
Radius is represented with "r"
Diameter is the line segment from one point on the circle, through the center of the circle, and to another point on the circle.
The Diameter is, therefore, twice the length of the radius!
Diameter is represented with "D".
The Diameter separates the circle into two, congruent, semi-circles.
A chord is a line segment from one point on a circle to another point on the circle that does not go through the center of the circle.
Circumference = Pi (3.14) x D
A circle contains 360 degrees
A semi-circle contains 180 degrees...
Please familiarize yourself with all the different parts and relationships in a circle!
Please know where Pi came from for tomorrow's quiz!
