The area of a circle is calculated using the formula A = πr² where r represents the radius. The constant π (pi) is approximately equal to 3.14159.
The circumference of a circle represents the distance around the circle. It is calculated using the formula C = 2πr.
The diameter is twice the radius and represents the longest distance across the circle.
Circle calculations are widely used in engineering, architecture, astronomy and many scientific applications.
