Radius of Area Sector Calculator

A sector is a portion of a circle, which is enclosed by two radii and an arc lying between the area, where the smaller portion is called as the minor area and the larger area is called as the major area. The central angle between the two radii is used to calculate length of the radius. The values of Length of the arc, the angle of surface is entered in the Radius of Area Sector Calculator. The calculator calculates the value and the resultant value of radius is displayed.

Formula:

r=L/2π*360/θ Where, r = Radius L = Length of Arc θ = Angle of Surface

Example:

A sector of angle 45 and length of the arc 3mm, find the radius of the sector.

Solution:

Formula: r=L/2π*360/θ
r = 3/(2(3.14))*360/45
r = 3/(2(3.14))*8
r = 3.8197
