a.98
b.49
c.77
d.126
Materi : Bangun Datar
Keliling ½ Lingkaran
K = ( π × d × ½ ) + d
K = ( 22/7 × 49 cm × ½ ) + 49 cm
K = ( 11 × 7 cm ) + 49 cm
K = 77 cm + 49 cm
K = 110 cm + 16 cm
{ K = 126 cm } [ d. ]
Semoga bisa membantu

Keliling Setengah Lingkaran
= ½ × π × d
= ½ × (22/7 × 49)
= ½ × (22 × 7)
= ½ × 154
= 77 cm
