Do you mean Sin(pi/2) = 1 or [Sin(pi)] /2 = 0.0274....
(pi*r2)/2 + 4000

the area of a circle is pi times radius2. half a circle is pi times radius2 divided by 2.
Area of a circle is: pi times radius squared
4 times pi times 4 divided by 2 is 78.9568352087
Do you mean Sin(pi/2) = 1 or [Sin(pi)] /2 = 0.0274....
Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.

Radius is the distance from the center point to the edge of the circle. Diameter is the distance straight through the center point and across the circle. Circumference is the distance one full turn around the circle. Radius = 1/2 of the diameter Radius = (circumference) divided by (2 pi) Diameter = 2 times the radius Diameter = (circumference) divided by (pi) Circumference = (pi) times the diameter Circumference = (2 pi) times the radius
