Penjelasan dengan langkah-langkah:
garis singgung persekutuan dalam = d
garis singgung persekutuan luar = L
jarak 2 pusat lingkaran = j
1) d = √(24² – (2+5)²)
d = √(576 – 49)
d = √527 cm
2) L = √(13² – (7 – 2)²)
L = √(169 – 25)
L = √144
L = 12 cm
3) r = [√(26² – 24²)] – 6
r = [√(676 – 576)] – 6
r = [√100] – 6
r = 10 – 6
r = 4 cm
4) r = 8 – √(13² – 12²)
r = 8 – √(169–144)
r = 8 – √25
r = 8 – 5
r = 3 cm
5) j = √(32² + (34–10)²)
j = √(1.024 + 576)
j = √1.600
