AB=√a² - (R - r)²
AB=√20² - (22 - 6)²
AB=√400 - 16²
AB= √400 - 256
AB= √144
AB= 12 cm
Jawab:
Diketahui :
jarak pusat lingkaran (p) = 20 cm
R = 22 cm
r = 6 cm
Ditanya : Panjang GSPL ?
Jawab :
d² = p² - (R - r)²
= 20² - (22 - 6)²
= 20² - 16²
= 400 - 256
= 144
d = √144
= 12 cm
Penjelasan dengan langkah-langkah:
" Life is not a problem to be solved but a reality to be experienced! "
