A decorative steel is shown and it is made from circular circle and 6 stems.
The length of each stem is 45cm.
Workout the total length of steel used in the frame

The total length of the steel used in the frame is 270 cm, if the decorative steel up of 6 stems and each stem is 45 cm.

Step-by-step explanation:

The given is,

           Decorative steel made from circular circle of 6 stems

           The length of the stem is 45 cm

Step:1

         We need to find the total length of the steel used in the decorative steel,

          Let,  T - Total length of the steel

                  L - Length of the stem

                  n - Number of stems used in steel frame

Step:2

       Formula to find the total length of the steel is,

                            ×

       From given,

                  = 45 cm

                  = 6 stems

       Substitute the values in formula,

                          ( 45 × 6 )

                              = 270

                        270 cm

Result:

         The total length of the steel used in the frame is 270 cm.
