1 dzień temu · The area of a corner or segment of a circle can be calculated using the formula: \ [ S = (1 - \frac {\pi} {4})r^2 \] where: \ (S\) is the area of the corner, \ (r\) is the radius of the circle.
5 dni temu · The formula to calculate the area of a quarter circle is derived from the area formula of a full circle. Given a circle with radius \(r\), the area of the quarter circle \(A\) is given by: \[ A = \frac{\pi r^2}{4} \]
4 dni temu · A line connecting any two points on a circle is called a chord, and a chord passing through the centre is called a diameter. The distance around a circle (the circumference) equals the length of a diameter multiplied by π (see pi). The area of a circle is the square of the radius multiplied by π.
