Jawaban:
a.8624 cm³
Penjelasan dengan langkah-langkah:
V = ⅓ × π × r × r × t
t = 42 cm
r = ⅓ × 42 = 14 cm
π = 22/7
V = ⅓ × 22/7 × 14 × 14 × 42
v = ⅓ × 22 × 2 × 14 × 42 (14 ÷ 7 = 2)
V = ⅓ × 44 × 588
V = ⅓ × 25872
V = 8624 cm³
Diketahui:
kerucut
r = 1/3 t
Ditanya:
V
Penyelesaian:
r = 1/3 t = 1/3 x 42 = 42/3 = 14 cm
V = 1/3 πr²t
= 1/3 x 22/7 x 14 x 14 x 42
= 22 x 2 x 14 x 14
= 8.624 cm³
Maka volume kerucut tersebut adalah 8.624 cm³ [a].

Diketahui:
kerucut
t = 42 cm
r = 1/3 t
Ditanya:
V
Penyelesaian:
r = 1/3 t = 1/3 x 42 = 42/3 = 14 cm
V = 1/3 πr²t
= 1/3 x 22/7 x 14 x 14 x 42
= 22 x 2 x 14 x 14
= 8.624 cm³
Maka volume kerucut tersebut adalah 8.624 cm³ [a].
