Verified answer
✔ Mapel = Matematika✔ Kelas = 8 SMP
✔ Materi = Lingkaran
✔ Kata kunci = Garis Singgung
Penyelesaian :
➡➡➡➡➡➡➡➡➡➡➡➡
p = 24 cm
r1 = 16 cm
r2 = 7 cm
Garis Singgung Persekutuan Luar
L² = p² - (r1 - r2)²
L² = 24² - (16-7)²
L² = 576 - 81
L² = 495
L = √495 cm
Semoga Membantu :)
Verified answer
L² = P² - (R-r)²dimana
L = pandang garis persekutuan luar
P = jarak pusat
R = jari jari lingkaran besar
r = jari jari lingkaran kecil
L² = 24² - (16-7)²
L² = 576 - 9²
L² = 576 - 81
L² = 495
L = √495 cm
