Circumference of a circle with radius 7 in
WebDec 22, 2024 · To calculate the radius of a circle, divide its circumference by 2π; for the circle's diameter, divide the circumference by π. Let's say that the circumference of a given circle is 20 inches. Therefore, its radius is 3.18 in and diameter 6.37 in. WebIf you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14. The formula for working out the circumference of a circle is: Circumference of circle = π x Diameter of circle. This is typically written as C = πd.
