WebQuestion The perimeter of a sector of a circle of radius 5.7 m is 27.2 m. Find the area of the sector. Medium Solution Verified by Toppr ⇒ Let OAB be the given sector. ⇒ And arcAB=l ⇒ Perimeter of sector OAB=OA+OB+arcAB ∴ 27.2=5.7+5.7+l ∴ l=27.2−11.4=15.8cm ⇒ Now, Area of sector OAB= 21×l×r ∴ Area of sector OAB= 21×15.8×5.7 WebSo the area of the sector over the total area is equal to the degrees in the central angle over the total degrees in a circle. And then we just can solve for area of a sector by multiplying both sides by 81 pi. 81 pi, 81 pi-- so these cancel out. 350 divided by 360 is 35/36. And so our area, our sector area, is equal to-- let's see, in the ...
