4. Di ketahui sebuah prisma dengan alas berbentuk segitiga dengan panjang alas 18 cm dan tinggi 15 cm. Jika tinggi prisma 12 cm, tentukan volume prisma!
Answer (5)
How much of the circle is clear ? 1/2 of it and 1/9 of it. How much of it is (1/2 + 1/9) ?
Before you can add fractions, they need to have the same denominator. The least common multiple of 2 and 9 is 18, so that's a good choice.
1/2 = 9/18
1/9 = 2/18
(1/2 + 1/9) = (9/18 + 2/18) = 11/18 . That's how much of the circle is NOT shaded.
Since 11/18 of it is NOT shaded, the remaining 7/18 of it is shaded.
1 − 9 1 − 2 1 = 18 18 − 18 2 − 18 9 = 18 7
To determine how much of a circle is clear, you must add 2 1 and 9 1 . The result of this addition, after finding a common denominator, shows that 18 11 of the circle is clear, and therefore 18 7 of the circle is shaded.

Jawaban:Diketahui:Alas prisma berbentuk segitigaPanjang alas segitiga = 18 cmTinggi segitiga = 15 cmTinggi prisma = 12 cmRumus volume prisma = luas alas × tinggi prismaLuas alas = ½ × alas × tinggi segitiga = ½ × 18 × 15 = 135 cm²Volume prisma = 135 × 12 = 1620 cm³✅ Jadi, volume prisma = 1620 cm³Penjelasan dengan langkah-langkah:Udah segitu dulu jawaban dariku semoga bermanfaat… jangan lupa dijadiin jawaban tercerdas yaaa
Penjelasan dengan langkah-langkah:Diketahui: - Alas segitiga = 18 cm - Tinggi segitiga = 15 cm - Tinggi prisma = 12 cm *Langkah 1: Hitung luas alas (segitiga)* Luas = ½ × alas × tinggi = ½ × 18 × 15 = 135 cm²*Langkah 2: Hitung volume prisma* Volume = luas alas × tinggi prisma = 135 × 12 = *1620 cm³**Jawaban: 1620 cm³*
