1. Prisma Segitiga V = Luas alas segitiga × tinggi prisma = a × t / 2 × t = 18 × 10 / 2 × 40 = 180/2 × 40 = 90 × 40 = 3600 cm3
2. Tabung V = Luas lingkaran × t tabung = phi r2 × t => r = 1/2 d = 1/2 × 14 = 7 cm = 22/7 × 7 × 7 × 15 = 22 × 7 × 15 = 154 × 15 = 2310 cm3 Semoga membantu yah.. dan jadikan jawaban terbaik bila kamu puas yah..
V = Luas alas segitiga × tinggi prisma
= a × t / 2 × t
= 18 × 10 / 2 × 40
= 180/2 × 40
= 90 × 40
= 3600 cm3
2. Tabung
V = Luas lingkaran × t tabung
= phi r2 × t
=> r = 1/2 d = 1/2 × 14 = 7 cm
= 22/7 × 7 × 7 × 15
= 22 × 7 × 15
= 154 × 15
= 2310 cm3
