Sector area and arc length formulas
WebCircle Sector is a two dimensional plane or geometric shape represents a particular part of a circle enclosed by two radii and an arc, whereas a part of circumference length called the arc. K-12 students may refer the below formulas of circle sector to know what are all the input parameters are being used to find the area and arc length of a circle sector. WebThe arc length is: L = θ × r (when θ is in radians) L = θ × π 180 × r (when θ is in degrees) Finding the Radius from Width and Height Say you know the width and height of an arc (maybe it is on the top of a door) and you want to make that arc using some string and a pencil ... what radius do you use? radius = height 2 + width2 8 × height
