Jari jari lingkaran A 4cm dan jari jari lingkaran B 2cm.jarak antara kedua pusatnya 10cm, hitunglah A.panjang GSPD B.panjang GSPL

A. GSPD = √10²-(2+4)² = √100-36 = √64 = 8 cm
B. GSPL = √10²-(4-2)² = √100-4 = √96 = 4√6 cm

Mapel Matematika
Bab PGSPL/D

a. PGSPD
=✓ j^2 - (R + r)^2
=✓ 10^2 - (4 + 2)^2
= ✓100 - 36
=✓ 64
= 8 cm

b. PGSPL
= ✓j^2 - (R - r)^2
= ✓10^2 - (4-2)^2
= ✓100 - 4
= ✓96
= 4✓6 cm
