Find the area of a sector of a circle whose radius is r and length of the arc is l. |
|
Answer» From formula ,Area of sector = 1/2×l.r area of sector = ?,radius= r, length=l.Arc length= theta/360 *2πr l=theta/180*πr area of sector=theta/360*2πr^ we write as area of sector= theta/2*180*πr*r= (theta /180*πr)*r/2=l*r/2 ans Iske bdd hi nhi ho raha h Pura find kijiye Area of sector = πr^2theta/360° |
