Penjelasan dengan langkah-langkah:

Diketahui:

Rumus Kerucut = ⅓ × π × r² × t

π = 22/7 jika jari-jari adalah kelipatan 7

π = 3,14 jika jari-jari bukan kelipatan 7

Ditanya bangun ruang a, b, c, d, e, f ?

Jawab:

A. Volume = ⅓ × π × r² × t

Volume = ⅓ × 22/7 × 14 × 14 × 20

Volume = ⅓ × 22 × 2 × 280

Volume = 4.106,66 cm³

B. Volume = ⅓ × π × r² × t

Volume = ⅓ × 3,14 × 5 × 5 × 12

Volume = ⅓ × 3,14 × 300

Volume = 314 cm³

C. Volume = ⅓ × π × r² × t

Volume = ⅓ × 3,14 × 10 × 10 × 18

Volume = ⅓ × 314 × 18

Volume = 1.884 cm³

D. Volume = ⅓ × π × r² × t

Volume = ⅓ × 3,14 × 15 × 15 × 20

Volume = ⅓ × 3,14 × 4500

Volume = 4.710 cm³

E. Volume = ⅓ × π × r² × t

Volume = ⅓ × 22/7 × 21 × 21 × 24

Volume = 11.088 cm³

F. Volume = ⅓ × π × r² × t

Volume = ⅓ × 22/7 × 14 × 14 × 21

Volume = 4.312 cm³
