Circumference of a circle based on radius
Did you know?
WebJan 2, 2024 · In Figure \(\PageIndex{1}\), the inner circle has a radius of 1, the outer circle has a radius of \(r\), and the angle shown has a measure of \(\theta\) radians. So the arc length on the unit circle subtended by the angle is \(\theta\), and we have used s to represent the arc length on the circle of radius \(r\) subtended by the angle. WebThe formulas for the circumference of a circle are given as follows: When the radius is given: Circumference of a circle formula = 2πr; When the diameter is given: Circumference of a circle formula = π × D; Where, r = radius of the circle. D = diameter of the circle. π = Pi with the value approximated to 3.14159 or 22/7. Radius of a Circle
WebSo radians are the constant of proportionality between an arc length and the radius length. It takes 2\pi 2π radians (a little more than 6 6 radians) to make a complete turn about the center of a circle. This makes sense, because the full circumference of a circle is 2\pi r 2πr, or 2\pi 2π radius lengths. WebMar 27, 2024 · Suppose you want to find the circumference of a 5 cm diameter circle. These would be the steps to follow: Use the appropriate equation, which, in this case, is the circumference to diameter formula: c = πd. Input the diameter in the equation: c = π × (5 cm) = 15.708 cm. That's it.
WebIf you know the diameter or radius of a circle, you can work out the circumference.
