А I. Identifying Parts of a Circle
A. Identify the parts of each circle.
1. Use the circle shown to answer each question
a. Name the circle.
b. Identify a radius of the circle.
c. Identify a diameter of the circle.
d. Identify a different diameter of the circle.
D

This is difficult to explain when there’s no diagram of a circle to refer to but I’ll try to explain the different parts of a circle
The diameter is the length of the line from one edge of the circle to the other that goes through the centre point (cut exactly in half)
The radius is the length of the line from the edge of the circle to the centre point (this means that the radius is half of the diameter)
The circumference is the length of the outside of the circle (like the perimeter of a circle)
An arc is a piece of the circumference (only part of the perimeter of the circle)
Let me know if there’s more to label and I’ll go through the other parts of a circle
