Ancient Greek amphitheatres were semicircular: a performance area with a semicircular area for the audience in front of it. Ancient Roman amphitheatres were circular or oval in shape with the audience surrounding the central performance area. The viewing area in most amphitheatres was tiered, natural or man-made, so that those at the back had a relatively clear view of the performance area.
You would find the area of the inside and outside shape (pretending that the inside shape was not in the outside shape). then, you would take the area of the outside shape and subtract the area of the inside shape.
Shape of what ?
A Protractor is a tool used to make circles.
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.
Such as? If you can break the shape up into triangles you can find the area that way. Or, you can get into calculus-based equations if you have an equation for the random shape.
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.
You times the length by width, to get the area of the 2D shape.
