WebThis is the reasoning: A circle has an angle of 2 π and an Area of: πr2. A Sector has an angle of θ instead of 2 π so its Area is : θ 2π × πr2. Which can be simplified to: θ 2 × r2. Area of Sector = θ 2 × r 2 (when θ is in radians) Area of … WebWhat is a Circle in Geometry? The word ‘circle’ is derived from a Greek word that means ‘hoop’ or ‘ring.’ In geometry, a circle is defined as a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center.” Never confuse a circle with a polygon.
