Penjelasan dengan langkah-langkah:
d² = p² - (r1+r2)²
d² = 25² - (8 + 7)²
d² = 625 - 15²
d² = 625 - 225
d = √400
d = 20 cm (a)
SOAL 1
___________________________________________
G Persekutuan Dalam = √P² - (r1 + r2)²
G Persekutuan Dalam = √25² - (8 + 7)²
G Persekutuan Dalam = √25² - 15²
G Persekutuan Dalam = √625 - 225
G Persekutuan Dalam = √400
G Persekutuan Dalam = 20 cm
