1. L.Gabungan dari ½ Lingkaran
= ( ½ × π × r² ) + ( ½ × π × r² )
= ( ½ × 22/7 × 28² ) + ( ½ × 22/7 × 10.5² )
= ( ½ × 22/7 × 784 ) + ( ½ × 22/7 × 110.25 )
= ( ½ × 2.464 ) + ( ½ × 346.5 )
= 1.232 + 173.25
= 1405.25 cm²

2. L.Gabungan dari ½ Lingakaran
= ( ½ × π × r² ) + ( ½ × π × r² )
= ( ½ × 3.14 × 27² ) + ( ½ × 22/7 × 10.5² )
= ( ½ × 3.14 × 729 ) + ( ½ × 22/7 × 110.25 )
= ( ½ × 2289.06 ) + ( ½ × 346.5 )
= 1144.53 + 173.25
= 1317.78 cm²
