The area of the (inside) of a circle - the circle itself is a line with no area - is calculated by:
pi * r2
the perimeter - also called the circumference is the length around the circle and is calculated:
2 * pi * r
where "r" is the radius, the distance from the center to the edge of the circle and "pi" is the irrational number 3.14159....
The perimeter of a circle is its circumference
If 'R' is the radius of the circle, then-- area of the circle is [ pi R2]-- perimeter of the circle is [ 2 pi R ]
Area of any circle = pi*radius2
No, it means the perimeter of the circle.
Of a circle,the area is: Pi * r^2,perimeter is: 2* Pi * rWhere, r is the distance from the circle's center to the perimeter, and Pi is a constant: Pi ~ 3.14.
zero is the least area and the max area, is of a circle of perimeter 40 .....
For a given perimeter, the circle has the largest area possible.
Using 3.14 as Pi the area of circle is: 0
Perimeter, I think.
It is called perimeter.
