Any point P with coordinates (\(x, y\)) on the circumference of a circle can be joined to the centre (0, 0) by a straight line that forms the hypotenuse of a right angle triangle with sides of length ...

As the tangent is a straight line, the equation of the tangent will be of the form \(y = mx + c\). We can use perpendicular gradients to find the value of \(m\), then use the coordinates of P to find ...

In this article, I will introduce to you the formula for calculating the area of a circle and the circumference of the circle most completely and accurately. Stay tuned. The circumference of a circle, ...

Enter the circle’s radius in the indicated field and select the dimension unit. Optionally, you can use the diameter and perimeter – circumference to calculate the circle’s area. If we have a circle ...
