Assume the shape is half circle.
The area of the circle is:
A = πr² where r is the radius
Since the semi circle has half the area of the circle, we obtain:
A = πr²/2

What shape is a amphitheatre?
Ancient Greek amphitheatres were semicircular: a performance area with a semicircular area for the audience in front of it.

How do you find the area if a shape that has uneven sides and different measurements?
Fill in the blanks so that the shape makes a square and find the area of that. Then find the area of the shape you added. When you have both areas, subtract the greater from the smaller.
Area of irregular shape?
To find the area, first divide the shape into regular, simple shapes. Then use formulas to find the area of the smaller, regular shapes. Lastly, add up all the smaller areas to find the area of the original shape.
