Radius of Inner Circle of Annulus given Area and Perimeter Solution

STEP 0: Pre-Calculation Summary

Formula Used

Inner Circle Radius of Annulus = ((Perimeter of Annulus/(2*pi))-(((Area of Annulus/pi))/((Perimeter of Annulus/(2*pi)))))/2
r_Inner = ((P/(2*pi))-(((A/pi))/((P/(2*pi)))))/2
This formula uses 1 Constants, 3 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Inner Circle Radius of Annulus - (Measured in Meter) - Inner Circle Radius of Annulus is the radius of its cavity and it is the smaller radius among two concentric circles.
Perimeter of Annulus - (Measured in Meter) - Perimeter of Annulus is defined as the total distance around the edge of the Annulus.
Area of Annulus - (Measured in Square Meter) - Area of Annulus is defined as the area of the ring-shaped space i.e. the enclosed region between the two concentric circles.

STEP 1: Convert Input(s) to Base Unit

Perimeter of Annulus: 100 Meter --> 100 Meter No Conversion Required
Area of Annulus: 200 Square Meter --> 200 Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

r_Inner = ((P/(2*pi))-(((A/pi))/((P/(2*pi)))))/2 --> ((100/(2*pi))-(((200/pi))/((100/(2*pi)))))/2

Evaluating ... ...

r_Inner = 5.95774715459477

STEP 3: Convert Result to Output's Unit

5.95774715459477 Meter --> No Conversion Required

FINAL ANSWER

5.95774715459477 ≈ 5.957747 Meter <-- Inner Circle Radius of Annulus

What is Annulus?

In mathematics, an Annulus (plural Annuli or Annuluses) is the region between two concentric circles. Informally, it is shaped like a ring or a hardware washer. The word "annulus" is borrowed from the Latin word anulus or annulus meaning 'little ring'. The adjectival form is annular (as in annular eclipse).The area of an Annulus is the difference in the areas of the larger circle of radius R and the smaller one of radius r.
