Penjelasan dengan langkah-langkah:
LM = L komidi putar sebenarnya(LS) × Skala
LM = πr² × [tex]\frac{1}{100}[/tex]
LM = (3,14 × 20²) × 10.000 × [tex]\frac{1}{100}[/tex]
LM = 1.256 × 10.000 × [tex]\frac{1}{100}[/tex]
LM = 12.560.000 × [tex]\frac{1}{100}[/tex]
LM = 125.600 cm²

Penjelasan dengan langkah-langkah:
Luas komidi putar pada model(LM):
LM = L komidi putar sebenarnya(LS) × Skala
LM = πr² × [tex]\frac{1}{100}[/tex]
LM = (3,14 × 20²) × 10.000 × [tex]\frac{1}{100}[/tex]
LM = 1.256 × 10.000 × [tex]\frac{1}{100}[/tex]
LM = 12.560.000 × [tex]\frac{1}{100}[/tex]
LM = 125.600 cm²
