6. Diketahui:
Volume prisma segitiga = 4.800 cm³
Panjang alas segitiga (a) = 24 cm
Tinggi prisma (t) = 50 cm
Ditanya: Tinggi segitiga (Δt) = ?
Dijawab:
V = Luas alas × t
= (½ × a × Δt) × t
4.800 = (½ × 24 × Δt) × 50
= 12 × Δt × 50
= 600 × Δt
Δt = 4.800 ÷ 600
= 8 cm
7. v kerucut = 1/3 x π x r² x t
12.474 = 1/3 x 22/7 x r² x 27
12.474 x 7 = 22 x r² x 9
87.318 : 198 = r²
441 = r²
√441 = r
21 = r
jari" = 21 cm
8. 10 cm³
Penjelasan dengan langkah-langkah:
volume balok= p x l x t= 3 x 2 x 1= 6 cm³
volume Limas segiempat= 1/3 x a x t= 1/3 x 6 x 2= 4 cm³
volume cetakan kue= volume balok + volume limas segiempat= 6 cm³+4cm³= 10cm³
