Question

What is the relation between area of triangle and area of circle

Answer 1

Answer:

In geometry, the area enclosed by a circle of radius r is π r2. Here the Greek letter π represents a constant, approximately equal to 3.14159, which is equal to the ratio of the circumference of any circle to its diameter.

One method of deriving this formula, which originated with Archimedes, involves viewing the circle as the limit of a sequence of regular polygons.Wheras,Triangle is also good to remember that the angle is always between the two known sides, called the "included angle".
