A math circle is an extracurricular activity intended to enrich students' understanding of mathematics. The concept of math circle came into being in the erstwhile USSR and Bulgaria, around 1907, with the very successful mission to "discover future mathematicians and scientists and to train them from the earliest possible age". [1]

Math Circles are communities focused on the enjoyment of mathematical problem solving. Meetings are lively, interactive, and often “funstrating”: challenging, but in a highly rewarding way!

In Maths or Geometry, a circle is a special kind of ellipse in which the eccentricity is zero and the two foci are coincident. A circle is also termed as the locus of the points drawn at an equidistant from the centre. The distance from the centre of the circle to the outer line is its radius.

Let us learn more about the circle definition, the circle formulas, and the various parts of a circle with a few circle practice problems on this page. What is Circle? A circle is a two-dimensional figure formed by a set of points that are at a fixed distance …

Mar 3, 2016 · Math circles are meetings between mathematicians and K-12 students or teachers where they work on problem solving. These gatherings typically take place outside the regular school...

Circle: the set of all points on a plane that are at a fixed distance from a center. The area of a circle is π times the radius squared, which is written: A = π r 2. Where. To help you remember think "Pie Are Squared" (even though pies are usually round): Example: What is the area of a circle with radius of 1.2 m ?

Circle: The set of all points on a plane that are a fixed distance from a center. Let us put a circle of radius 5 on a graph: Now let's work out exactly where all the points are. We make a right-angled triangle: And then use Pythagoras: We can use that idea to find a missing value. Example: x value of 2, and a radius of 5. y ≈ ±4.58...

A circle is a round-shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed shape, two-dimensional shape, curved shape. A few things around us that are circular in shape are a car tire, a wall clock that tells time, and a lollipop.
