Radius of a circle from diameter
WebJan 24, 2024 · Radius of a circle is any line from the center of the circle to the circumference of the circle. A diameter is the sum of two radius within the circle. Any line apart from the diameter inside the circle is referred to as a chord. The radius of a circle is used for the purpose of calculating the area and circumference of the circle. WebThe circumference – the length of the outside boundaries of the circle. To find the area from the radius, it's very easy. a=\pi r^2 a = πr2. Diameter is just 2x radius, so to get the circle's area from the diameter: a=\pi (d/2)^2 a = π(d/2)2. And to find area from circumference, it's easiest to first conve. r=c/2\pi \\ a = \pi r^2 r = c/2π ...
