Area of Elliptical Sector Solution

Follow our step by step solution on how to calculate Area of Elliptical Sector?

FIRST Step Consider the formula
ASec=(aSectorbSector2)(Sector-atan((bSector-aSector)sin(2Leg(2))aSector+bSector+((bSector-aSector)cos(2Leg(2))))+atan((bSector-aSector)sin(2Leg(1))aSector+bSector+((bSector-aSector)cos(2Leg(1)))))
Next Step Substitute values of Variables
ASec=(10m6m2)(90°-atan((6m-10m)sin(2120°)10m+6m+((6m-10m)cos(2120°)))+atan((6m-10m)sin(230°)10m+6m+((6m-10m)cos(230°))))
Next Step Convert Units
ASec=(10m6m2)(1.5708rad-atan((6m-10m)sin(22.0944rad)10m+6m+((6m-10m)cos(22.0944rad)))+atan((6m-10m)sin(20.5236rad)10m+6m+((6m-10m)cos(20.5236rad))))
Next Step Prepare to Evaluate
ASec=(1062)(1.5708-atan((6-10)sin(22.0944)10+6+((6-10)cos(22.0944)))+atan((6-10)sin(20.5236)10+6+((6-10)cos(20.5236))))
Next Step Evaluate
ASec=34.1432054805833
LAST Step Rounding Answer
ASec=34.1432
