1. V = 1,232dm³

2. t = 16cm

3. V = 1.920cm³

Penjelasan dengan langkah-langkah:

1. r = 7cm

t = 24cm

V = ⅓πr²t

= ⅓ × 22/7 × 7cm × 7cm × 24cm

= ⅓ × 3.696cm³

= 1.232cm³

= 1.232cm³ : 1.000

= 1,232dm³

2. p = 23cm

l = 14cm

V = 5.152cm²

V = p × l × t

5.152 = 23 × 14 × t

5.152 = 322t

t = 5.152/322

t = 16cm

4. a = 12cm

t = 8cm

t. prisma = 40cm

V = Luas alas × t. prisma

= ½at × 40cm

= ½ × 12cm × 8cm × 40cm

= 48cm² × 40cm

= 1.920cm³
