Note that a value of theta of 180 degrees leads to pi (R squared)/2, or one half the area of a circle.

What is 2 pi squared?
The formula for double the area of a circle
What is the formula for finding circumference and area of a circle?
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
What is circle's area formula?
The formula for the area of a circle is: Area = π x r2 (r is the radius and Pi is about 3.1416). The result is expressed in square units.
What is Pi R Squared?
The formula for the area of a circle is πr^2, where π (pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. So, "pi r squared" refers to the area of a circle, calculated by multiplying π by the square of the radius. This formula is fundamental in geometry and mathematics for finding the area enclosed by a circle.
What formula is apply to find area of semi circle?
If the radius of the circle is R, then the area of the whole circle is πR2 So the area of the semicircle is 0.5*πR2
