Jawaban:

diketahui :

jari-jari :12 cm

tinggi : 8 cm

ditanya :

Volume : ?

Jawab :

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

$sf{}v = frac{1}{3} times 3,14 times 12 times 12 times 8$

$sf{}v = frac{1}{ cancel3} times 3,14 times cancel {12}^{4} times 12 times 8$

$sf{}v = 1 times 3,14 times 4 times 12 times 8$

$sf{}v = 3,14 times 4 times 12 times 8$

$sf{}v = 12,56 times 12 times 8$

$sf{}v = 150.72 times 8$

$sf{}v = 1.205,76 {cm}^{3}$

Jawaban:

r = 12 cm

t = 8 cm

Maka:

V = ⅓ πr²t

V = ⅓ × 3,14 × 12² × 8

V = ⅓ × 3,14 × 144 × 8

V = 1.205,76 cm²
