Diketahui:
D= 9 cm
P= 15 cm
R1= 8 cm
Ditanya : panjang jari-jari lingkaran lainnya?
Jawab =
(R1 + R2)² = p² - d²
(R1 + R2)² = 15² - 9²
(R1 + R2)² = 225 - 81
(R1 + R2)² = 144
(R1 + R2) = √144
(R1 + R2)² = 12
=> (R1 + R2)² = 12 - 8 = 4cm
maaf kalo salah
Penjelasan dengan langkah-langkah:
d = 9 cm
p = 15 cm
r1 = 8 cm
r2 = ...
d² = p² - (r1 + r2)²
9² = 15² - (r1 + r2)²
(r1 + r2)² = 15² - 9²
(r1 + r2)² = 225 - 81
(r1 + r2)² = 144
r1 + r2 = 12
8 + r2 = 12
r2 = 12 - 8
r2 = 4 cm
