Circle Circumference Calculator Circle Circumference Calculator As we know that in geometry we study about planes, points, space, lines etc and as we know that geometry is sub divided into two types two dimensional and three dimensional. Now in 2 d we study about the surfaces which have only two planes and denoted by x and y and the examples of 2d are rectangle, triangle, square, circle etc and in 3d we study about those surfaces which are having three planes x, y and z and the example are sphere, cylinder, cube etc. Now we know that circle is 2d surface or we can say flat surface and it is a closed shape and in this the distance of all the points are same from its origin point. Now there are few terms related to circle and they are Origin point is the point which is situated at the centre of circle and it is also called centre point. If we join any point on circumference to its centre then this line is called radius and twice of radius is called diameter and diameter is always passed from origin point.

If a line joining two points on circumference of circle and lies inside the circle are called chord and diameter is the largest chord. Suppose that any line touches a point of circle and perpendicular to radius of circle is called tangent of circle. Now circumference of circle means the outer boundary of circle. The formula of circumference of circle is Circumference of circle = 2πr Where π = pie = constant and r = radius of circle. Now we have to study about circumference of a circle calculator. Suppose that we have a circle whose radius is 10 cm and now find out the circumference of circle. So we have radius (r) = 10 cm And π = 22/7. Now put all the values in formula of circumference of circle. Circumference of circle = 2πr Circumference of circle = 2 × (22/7) × 10 Circumference of circle = 440/7 Read More About : How To Do Percentages

So, circumference of circle = 62.857 cm This is the total distance of boundary of circle and this boundary is called circumference of circle. Now taking another example in which diameter of circle is given and we have to find out the circumference of circle. Suppose that there is a circle and its diameter is 40 cm and we have to find the circumference of circle. Now first we have to find the radius of circle So diameter is twice of circle d = 2r So, r = d/2 R = 40/2, r = 20 cm Now we have value of radius so next step is put all the values in the formula of circumference Circumference of circle = 2πr Circumference of circle = 2 × (22/7) × 20 Circumference of circle = 880/7 Circumference of circle = 125.714 cm So this is the final result and the value of circumference of circle is 125.714 cm and we can also find the radius if the circumference value is given and by the above discussion we find that it is very easy to find the circumference of circle.
