Question

If the perimeter of a sector of circle of radius 6.5 cm is 29 cm, then the area of sector is

Answer 1

I think you mistake ly right 29 but here 31 then the solution is Let OPQ be the sector of the circle whose center is at O and radius is 6.5 cm. Also, let the angle POR be θ.



Now length of the arc PQ



Perimeter of the sector OPQ = OP + arc PQ + QO



Area of the sector (OPQ) =

Area of the sector (OPQ) = 58.5 cm2 I hope it true but when in question 29 is given then we replace the 31 and put 29 then solve step by step
