The circumference ( C ) of a circle is calculated using the formula ( C = 2\pi r ), where ( r ) is the radius of the circle. The area ( A ) of a circle is given by the formula ( A = \pi r^2 ). In both formulas, ( \pi ) (pi) is a constant approximately equal to 3.14159.
It is important to know formulas of pi for circles like areas of a circle and its circumference
Using 3.14 as Pi the area of circle is: 0
Yes
Pi is the number you get after finding the ratio of a circle's radius to its circumference. It's used in formulas to find the circumference and area of circles. The number goes on infinitely, but most people abbreviate the decimal to 3.14.
A square can't have a circumference. That's only for circles squares have area, volume, or perimeter.
The derivative of a circles area is it's circumference.

Circumfrences are only for circles.

Because of the radius of the circle
The title of the picture is "Circumference and Area of Circles" on page D-60. It's not rocket science, darling. Just turn to page D-60 and feast your eyes on the wonders of circles. You're welcome.
It's important to know the formulas for all these characteristics of circles, and to recognize what they have in common. Area of a circle = πr2 Circumference of a circle = 2πr or dπ Where in the above equations r represents radius, and d is diameter (2r). Both these equations have r in them. Find the radius using the circumference equation, and then plug it into the equation for Area
Area= square the radius and times it by pie
