👉 Metreta is a term used in mathematics and physics to represent the area of a circle, which is also known as the area under a curve. In this context, "metreta" refers to the square root of π (pi) divided by 27. The area of a circle with radius r can be calculated using the formula A = πr^2. For example, if you have a circle with a radius of 3 units, its area would be approximately 9π square
