Define circumference and area of a circle
Answers
Answer:
Circumference of the circle or perimeter of the circle is the measurement of the boundary across any two-dimensional circular shape including circle. Whereas the area of circle, defines the region occupied by it. If we open a circle and make a straight line out of it, then its length is the circumference.
Circumference of Circle: 2πr
Area of circle: πr2

Answer:
In geometry, the circumference (from Latin circumferens, meaning "carrying around") of a circle is the (linear) distance around it. That is, the circumference would be the length of the circle if it were opened up and straightened out to a line segment.
In geometry, the area enclosed by a circle of radius r is π r². Here the Greek letter π represents a constant, approximately equal to 3.14159, which is equal to the ratio of the circumference of any circle to its diameter.
