What is a ring and how its perimeter is calculated?

A circular ring (annulus) is a plane figure bounded by the circumference of two concentric circles of two different radii. Its perimeter is calculated by the formula P = 2 π ( R+r) where P is the perimeter, R is the biggest radius of the circle among the concentric circles and r is the smallest radius of the circle among the concentric circles.

How to Calculate Perimeter of a ring?

Perimeter of a ring calculator uses Perimeter=2*pi*(Outer Radius+Inner Radius) to calculate the Perimeter, Perimeter of a ring is the sum of the length of the ring all around. Perimeter and is denoted by P symbol.

How to calculate Perimeter of a ring using this online calculator? To use this online calculator for Perimeter of a ring, enter Outer Radius (R) and Inner Radius (r) and hit the calculate button. Here is how the Perimeter of a ring calculation can be explained with given input values -> 0.942478 = 2*pi*(0.1+0.05).

FAQ

What is Perimeter of a ring?
Perimeter of a ring is the sum of the length of the ring all around and is represented as P=2*pi*(R+r) or Perimeter=2*pi*(Outer Radius+Inner Radius). Outer Radius is the radius of the larger of the two concentric circles that form its boundary and Inner Radius of any figure is the radius of its cavity. It is the smaller radius among two concentric circles.
How to calculate Perimeter of a ring?
Perimeter of a ring is the sum of the length of the ring all around is calculated using Perimeter=2*pi*(Outer Radius+Inner Radius). To calculate Perimeter of a ring, you need Outer Radius (R) and Inner Radius (r). With our tool, you need to enter the respective value for Outer Radius and Inner Radius and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
