Tolong jawab yg nomor 17 dan 18. Pakai caranya ya...

17.
Luas 2 Segitiga :
L = 2 × ½ × a × t
L = 10 × (24 - 12)/2
L = 10 × 12/2
L = 10 × 6
L = 60 cm²

Luas Persegi Panjang :
L = p × l
L = 12 × (10 - 2 - 2)
L = 12 × 6
L = 72 cm²

Luas Gabungan :
L = 72 cm² + 60 cm²
L = 132 cm²

Jawaban : a. 132 cm²

18.
Volume Tabung :
V = πr²t
V = 22/7 × 14 × 14 × 15
V = 22 × 2 × 14 × 15
V = 44 × 14 × 15
V = 44 × 210
V = 9.240 cm³

Jawaban : d. 9.240 cm³

Maaf Kalau Salah

Jawabannya;
18. V. tabung= Πr^2t
v= 22/7. 14. 14. 15
v= 22. 2. 14. 15
v= 44. 14. 15
v= 616. 15
v= 9240 cm^3 ----- D

# no 17 sya krg tau,, maaf ya

SEMOGA MEMBANTU
