Diameter
The diameter of a circle is a straight line that passes through the center of the circle and touches two points on the circle's circumference. It is the longest chord of the circle and is equal to twice the length of the radius.
Key Points about Diameter:
- The diameter is a line segment that passes through the center of a circle.
- It is the longest chord of the circle.
- The length of the diameter is double the length of the radius.
- The formula to find the diameter of a circle is: d = 2r, where d is the diameter and r is the radius.
Study Guide:
Here are some study questions to help you understand the concept of diameter:
- What is the definition of diameter?
- How is the diameter related to the radius of a circle?
- Is the diameter always the longest chord of a circle? Why or why not?
- What is the formula to find the diameter of a circle?
- If the radius of a circle is 5 cm, what is the diameter?
By understanding the concept of diameter, you will be able to solve problems related to circles and their properties.
