Penjelasan dengan langkah-langkah:

NOMOR 1

Volume Tabung :

• V › = La x t
• V › = πr²t

_________

• r › = 7 cm

• t › = 20 cm

Volume Tabung :

V Tabung › = πr²t

V Tabung › = 22/7 x 7 cm x 7 cm x 20 cm

V Tabung › = 22 x 7 cm x 20 cm

V Tabung › = 154 cm x 20 cm²

V Tabung › = 3.080 cm³

NOMOR 2

Volume Prisma Segitiga :

• V › = La x t
• V › = ½ x (a x t) x t prisma

____________

• a › = 8 cm

• t › = 7 cm

• t prisma › = 25 cm

Volume Prisma Segitiga :

V Prisma ∆ › = ½ x (a x t) x t prisma

V Prisma ∆ › = ½ x (8 cm x 7 cm) x 25 cm

V Prisma ∆ › = ½ x 56 cm² x 25 cm

V Prisma ∆ › = ½ x 1.400 cm²

V Prisma ∆ › = 700 cm³

NOMOR 3

Volume Kerucut :

• V › = ⅓ x La x t
• V › = ⅓ x πr² x t

____________

• r › = 15 cm

• t › = 14 cm

Volume Kerucut :

V Kerucut › = ⅓ x πr² x t

V Kerucut › = ⅓ x 3,14 x 15 cm x 15 cm x 14 cm

V Kerucut › = ⅓ x 706,5 cm² x 14 cm

V Kerucut › = ⅓ x 9.891 cm²

V Kerucut › = 3.297 cm³
