Jawab:
Segitiga dan lingkaran
Lingkaran " didalam "segitiga
r (lingkaran ) = Luas segitiga / 1/2 keliling segitiga
r = L/s
Penjelasan dengan langkah-langkah:
1) a= 5, b = 13, c = 12 -> adalah triple pitagoras (Δ siku siku)
L = 1/2 (5)(12) = 30
S= 1/2 ( a+ b+ c) = 1/2 (30) = 15
r= 30/15
r= 2
2) a = 6, b = 10 , c = 8 --> adalah triple pitagoras (Δ siku siku)
L = 1/2 (6)(8) = 24
s = 1/2 ( a + b + c ) = 12
r = 24/12
r = 2
