Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
To calculate the area of a circle use this formula: pi x r2.
A circle is two dimensional, it has area but not volume.
The center of a circle.
The answer depends on what characteristic of a half circle you want to calculate: its area or perimeter or something else.

Radius of a circle is half the diameter. For any given circle draw a straight line from one point on the circulference, through the circle centre, to the opposite point on the circu,afenrece. Then taking a rule measure the straight line distance. That is the diameter(d) Half of this distance, that from the circle dentre to the circumference is the radius(r). r + r = d or 2r = d or r = d/2 From this straight line we can calculate both the area (A)and the circuference(C) by using the following eq'ns/ C = 2pir = pi*d A = pi *r^(2) 'pi' is a constant for all circles. and the number 3.14 or 3.1416 or 22/7 are used in these APPROXIMATIONS.
Radius of a circle = diameter/2
Each circle with a different radius (or diameter or circumference) is a different size circle.
Width Of Circle X 3.14 or PII
A circle is two dimensional, it has area but not volume.

Enlarge your mouse size to the size you want for the circle. Then click to make the circle. If you want a hollow circle then make the mouse smaller then delete.
To calculate the area of a circle, you can use the formula A = πr^2, where A is the area and r is the radius of the circle. Simply square the radius, multiply it by π (approximately 3.14159), and you will have the area of the circle.
A simple formula to calculate the circumference of a circle: so in this case:
