Kelas 8 MatematikaBab Garis Singgung Lingkaran
R - r = √(jarak pusat² - garis singgung²)
31/2 - r = √(26² - 24²)
-r = - 31/2 + √(676 - 576)
r = 31/2 - √100
r = 31/2 - 10
r = 31/2 - 20/2
r = 11/2 cm
Verified answer
≡ penyelesaian :⇔sudah diketahui ( R - r ) = 10 cm, maka :
maka,jari jari lingkaran yang lain adalah 11/2
