## Radius of large circle of annulus given small circle radius and perimeter Solution

STEP 0: Pre-Calculation Summary
Formula Used
radius_of_large_circle = (perimeter of annulus/(2*pi))-(Radius of small circle)
R = (P/(2*pi))-(r)
This formula uses 1 Constants, 2 Variables
Constants Used
pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288
Variables Used
perimeter of annulus - Perimeter of annulus is defined as the sum of outermost part of the annulus (Measured in Meter)
Radius of small circle - Radius of small circle is defined as the inner radius of the given polygon (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
perimeter of annulus: 20 Meter --> 20 Meter No Conversion Required
Radius of small circle: 2 Meter --> 2 Meter No Conversion Required

## 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
