Definitions of Key Terms: Homework 1 Parts Of Circles Area & Circumference
A circle is a two-dimensional shape defined by a fixed point called the center and a constant distance from the center to any point on the circle, known as the radius. It is a closed, symmetrical figure with no corners or edges.
Area refers to the amount of two-dimensional space enclosed within the boundary of a circle. Circumference, on the other hand, measures the perimeter or the distance around the circle.
Formulas for Area and Circumference
The formula for calculating the area of a circle is:
A = πr2
where:
- A is the area of the circle
- π (pi) is a mathematical constant approximately equal to 3.14
- r is the radius of the circle
The formula for calculating the circumference of a circle is:
C = 2πr
where:
- C is the circumference of the circle
- π (pi) is a mathematical constant approximately equal to 3.14
- r is the radius of the circle
