Kelas 8 MatematikaBab Lingkaran
Karena 5, 12, 13 adalah Tripel Pythagoras, maka ini adalah segitiga siku-siku.
s = 1/2 . jumlah seluruh sisi
s = 1/2 . (5 + 12 + 13)
s = 1/2 . 30
s = 15 cm
r = L/s
r = (1/2 . a . t)/15
r = (1/2 . 5 . 12)/15
r = 2 cm
Verified answer
Jawabans = 1/2 . [5 + 12 + 13]
= 15 cm
r = [1/2 . a . t]/15
= [1/2 . 5 . 12]/15
= 2 cm
lingkaran dalam segitiga ABC adalah 2cm
