R = 8 cm
r = 3 cm
P = 13 c,
dit : GL ?
MAKA :
GL² = P² - (R-r)²
GL² = 13² - (8-3)²
GL² = 169 - 25
GL = √144
GL = 12 CM
JDI panjng brs singgung persekutuan luar = 12 cm
R = 8cm
r = 3cm
d = 13cm
Dit: garis singgung persekutuan luar (l)
l² = d² - (R-r)²
l² = 13² - (8-3)²
l² = 13² - 5²
l² = 169 - 25
l² = 144
l = √144
l = 12 cm
