Yang no 8 sampek 13, tolong dijawab ya kawan

9. AB = √26²-10² = √676-100 = √576 = 24 cm
10. Luas = 10x24/2 = 120 cm²
11. CD = √17²-(10-2)² = √289-64 = √225 = 15 cm
Luas = (2+10)/2 x 15 = 90 cm²
12. 5s + 4s = √30²-24² = √900-576 = √324
9s = 18
s = 18/9
s = 2
R1 = 5x2 = 10 cm
R² = 4x2 = 8 cm
13. PTM = 2x20x(6+3,14)
= 40 x 9,14
= 365,6 cm
