How do you work out the diametre of a shape?

Answer 1

To calculate the diameter of a shape, you first need to identify the shape type. For a circle, the diameter is twice the radius, which can be found using the formula (D = 2r). For other shapes, like an ellipse, the diameter can vary depending on the axes, but is typically defined as the longest distance across the shape. In polygons, the diameter can be the longest distance between any two vertices.
