$\huge\color{purple} Answer$

• In geometry, the circumference (from Latin circumferens, meaning "carrying around") is the perimeter of a circle or ellipse.
• That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment.

• The formula for the circumference of a circle is the product of pi (π) and the diameter or twice the product of pi (π) and the radius.
• Example: Find the circumference of the circle with a diameter of 8 inches. Answer: The circumference of the circle is 8π ≈ 25.163 inches.

• Using the formula C = π d C = \pi d C=πd. That's it! We can just leave our answer like that in terms of π.
• So, the circumference of the circle is 10 π 10 \pi 10π units.

• Circumference of the circle or perimeter of the circle is the measurement of the boundary of the 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.
• It is usually measured in units, such as cm or unit m.
