tolong ini darurat + penting

6. Jari jari = R = 13,r=3
jarak = 26 cm

Sl²=j²-(R-r)²
Sl²=26²-(13-3)²
Sl²=676-100
Sl=√576
Sl=24 cm

7.Jarak =26 cm
jari jari (r)=4 cm
Sl = 24 cm

(R+r)²=J²-Sl
(R+4)²=26²-24²
(R+4)²=676-576
(R+4)=√100
R = 10+4
R=14

8. Diameter=42,Jari jari =21
besar sudut pusat = 270°

besar s.pusat/360°=p.busur/keliling lingk
270°/360°=p.busur/2×22/7×21
3/4=p.busur/132
132×3=p.busur × 4
396÷4=p.busur
p.busur= 99 cm

9.Sl=16 cm
jari jari=R=17,r=5

J²=Sl²+(R-r)²
J²=16²+(17-5)²
J²=256+144
J=√400
J=20 cm

#Semoga membantu :)
