Find area, circumference & diameter of circle |
3.14 π (पाई) का मान है
7 वृत्त का त्रिज्या (radius) है
और हम वृत्त का क्षेत्रफल (Area of Circle) निकाल रहे हैं
वृत्त का क्षेत्रफल निकालने का सूत्र होता है: Area = π × r × r यानि Area = 3.14 × 7 × 7 = 153.86 वर्ग इकाई
तो इसका मतलब है कि आप एक ऐसे वृत्त का क्षेत्रफल निकाल रहे हैं जिसकी त्रिज्या 7 है, और उसका क्षेत्रफल 153.86 होगा।
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. Diameter is the line which divides the circle into two equal parts and is also equal to twice of the radius.
Centre – It is the midpoint of a circle.
Chord- A line segment whose endpoints lie on the circle.
Diameter- A line segment having both the endpoints on the circle and is the largest chord of the circle.
Radius- A line segment connecting the centre of a circle to any point on the circle itself.
Secant- A straight line cutting the circle at two points. It is also called an extended chord.
Tangent- A coplanar straight line touching the circle at a single point.
Area =π r2
Circumference of a Circle = 2πr units
