PERIMETER OF A SEMI CIRCLE A7


Find the perimeter of the following semi-circle.



Solution

Perimeter = ∏D + D
                      2

Perimeter = ( 1122  X 1498 )    +  98
                      17         12

                = (11 x 14 ) + 98

                = 156 + 98

                = 254


Hence perimeter is 254 cm
