Formula, Definition, Area of Sector of Circle

Area of sector = θ 360 × π r 2 Derivation: In a circle with centre O and radius r, let OPAQ be a sector and θ (in degrees) be the angle of the sector. Area of the circular region is πr². Let this

Area Of A Sector And Segment

You can also find the area of a sector from its radius and its arc length. The formula for area, A A, of a circle with radius, r, and arc length, L L, is: A = (r × L) 2 A = ( r × L) 2. Here is a three-tier birthday cake 6 6 inches tall with a diameter of
