Quiz

V = 1/3 × π × r² × t

= 1/3 × 22/7 × 7² × 10

= 1/3 × 22/7 × (7 × 7) × 10

= 1/3 × 22 × 7 × 10

= 1/3 × 154 × 10

= 1/3 × 1540

= 1540/3

= 513,3 cm³

PEMBAHASAN

Rumus Volume Kerucut:

$v = frac{1}{3} times L.alas times t$

$v = frac{1}{3} times pi times {r}^{2} times t$

Diketahui:

r = 7 cm

t = 10 cm

Ditanya:

v = …

Jawaban:

$v = frac{1}{3} times pi times {r}^{2} times t$

$v = frac{1}{3} times frac{22}{7} times {7}^{2} : cm times 10 : cm$

$v = frac{1}{3} times 22 times 7 times 10$

$v = frac{1540}{3}$

$v = 513,3 : {cm}^{3}$

Jadi, Volume Kerucut tersebut adalah 513,3 cm³
