the line passing through the center of the circle, touching two points on its
boundary is known as the

the perimeter or total distance around the circle is referred to as the

a line segment whose end points both lie on the circles circumference is called a

the area of a circle is calculated using the formula ( a=pi r^{2} ), where
\ stands for

Explanation:

• The distance from the center of a circle to its edge is a fundamental geometric property defined as the radius.
• A line passing through the center and touching two points on the boundary is the diameter, which is twice the radius.
• The perimeter around a circle is called the circumference.
• A line segment with endpoints on the circumference is a chord.
• In the area formula \(A = \pi r^{2}\), \(r\) represents the radius.

Answer:

1. radius
2. diameter
3. circumference
4. chord
5. radius
