Question

area of the minor sector is 150 and radius 5 then find arc lenth
​

Answer 1

Answer:

length of arc= thetha /360*2 pie r

Step-by-step explanation:

area of sector = thetha/360 pie r sq.

150/25*7/22/360

Answer 2

Answer:

Step-by-step explanation:

area of sector= 150 sq. unit

radius=5 unit

area of sector = Ф/360 *π r^2

              150          =  Ф/360  *22/7  *5*5

               150/5   *7/22  =   Ф/72

                 30*7/22 *72= Ф

                105/11  *72 =Ф

length of an arc=  Ф/360 *2πr

                         = 105/11  *72 *22/7 *5*2

                          = 15*72*10*2

                           =  30*72*10

                           = 300*72

                           =  21600 unit
