D = 24 CM
P = 26 CM
R = 6 cm
maka :
(R+r)² = P² - D²
(6+r)² = 26² - 24²
(6+r)² = 676 - 576
6+r = √100
6+r = 10
r = 10-6
r = 4 cm
jadi pnjng jari2 y lain = 4 cm
p = 26 cm
R = 6
r = ?
d² = p² - (R + r)²
24² = 26² - (6 + r)²
(6 + r)² = 26² - 24²
(6 + r)² = 676 - 576
(6 + r)² = 100
6 + r = 10
r = 10 - 6
r = 4 cm
semoga membantu ya :)
