V tabung = 1.540 cm³
Jika t = 10 cm
r (jari jari) = ??

Penjelasan dengan langkah-langkah:

Jawaban :

r = V ÷ (π × t)

r = 1.540 ÷ (22/7 × 10)

r = 1.540 ÷ 220

r = 7 cm

I hope this help :)

Penjelasan dengan langkah-langkah:

V tabung = 1.540 cm³

Jika t = 10 cm

r (jari jari) = ??

penyelesaian :

$\sf \: v = \pi r {}^{2} .t$

$\sf \: r = v \div (\pi \times t)$

$\sf \: v = \frac{22}{7} \times r {}^{2} \times 10$

$\sf1.540 = \frac{22}{7} \times {r}^{2} \times 10$

$\sf r = 1.540 \div( \frac{22}{7} \times 10)$

$\sf \: r = 1.540 \div \frac{220}{7}$

$\sf\: r = 1.540 \times \frac{7}{220}$

$\sf \: r = \frac{1.540 \times 7}{220}$

$\sf \: r = \frac{10.780}{220}$

$\sf r= 49$

$\sf {r}^{2} = 49 \\ \sf {r}^{2} = {7}^{2} \\ \sf {r}^{ \cancel2} = {7}^{ \cancel2} \\ \sf \: \color{red} r = 7$
