PERIMETER SEMI CIRCLE A1


Find perimeter of the figure below



Solution

Perimeter = ∏D + D
                    2

              = ( 1122  X 1070 )    +  70
                    17            12

              = (11 x 10 ) + 70

              = 110 + 70

              = 190


Hence perimeter is 190m
