JANGAN NGASAL ​

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

j = 40 cm
