Question

the length of certain sector of a circle of radius 5.6 cm is 17.2 cm find the radius of the sector

Answer 1

The raidus of circle =5.6 cm

Therefore the raidus of setor of circle= 5.6 cm

if area of sector is to be found:

Length of sector = 17.2 cm

radius of sector= 5.6 cm

Therefore , area of sector i= 1/2 x l x r

                                              =1/2 x 17.2 x 5.6

                                               =48.16 cm²
