Area of Annulus Sector Solution

STEP 0: Pre-Calculation Summary
Formula Used
Area of Annulus Sector = (Outer circle radius of Annulus^2-Inner circle radius of Annulus^2)*(Central angle of Annulus Sector/2)
AAnnulus Sector = (rOuter(Annulus)^2-rInner(Annulus)^2)*(θCentral Angle(Annulus)/2)
This formula uses 4 Variables
Variables Used
Area of Annulus Sector - (Measured in Square Meter) - Area of Annulus Sector is the total region covered between the outer and the inner circle of the Annulus Sector.
Outer circle radius of Annulus - (Measured in Meter) - Outer circle Radius of Annulus is the radius of a larger circle of the two concentric circles that form its boundary.
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.
Central angle of Annulus Sector - (Measured in Radian) - Central angle of annulus sector is the angle whose apex (vertex) is the center of the concentric circles of Annulus and whose legs (sides) are radii intersecting the circles in four distinct points.
STEP 1: Convert Input(s) to Base Unit
Outer circle radius of Annulus: 10 Meter --> 10 Meter No Conversion Required
Inner circle radius of Annulus: 6 Meter --> 6 Meter No Conversion Required
Central angle of Annulus Sector: 30 Degree --> 0.5235987755982 Radian (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
AAnnulus Sector = (rOuter(Annulus)^2-rInner(Annulus)^2)*(θCentral Angle(Annulus)/2) --> (10^2-6^2)*(0.5235987755982/2)
Evaluating ... ...
AAnnulus Sector = 16.7551608191424
STEP 3: Convert Result to Output's Unit
16.7551608191424 Square Meter --> No Conversion Required
FINAL ANSWER
16.7551608191424 Square Meter <-- Area of Annulus Sector

What is an Annulus Sector?

An Annulus Sector, also known as the circular ring sector, is a cut piece from an Annulus that is joined by two straight lines from its center.

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
