Penjelasan dengan langkah-langkah:

$v = pi times {r}^{2} times t \ v = frac{22}{7} times 7 times 7 times 20 \ v = 3080$

2. 22liter = 22.000 cm³

$v = pi times {r}^{2} times t \ 22000 = frac{22}{7} times {r}^{2} times 70 \ 22000 = 220 times {r}^{2} \ {r}^{2} = frac{22000}{220} \ {r}^{2} = 100 \ r = sqrt{100} \ r = 10$

3. V = 1/3 × π × r² × t

V = 1/3 × 22/7 × 7 × 7 × 24

V = 22×7×8

V = 1.232
