Question

Find the volume of cylinder having radius 3.5 cm height 10cm

Answer 1

Answer:

Given, r = 3.5 cm h = 40 cm By using the formula, Volume of a cylinder = πr2h = 22/7 × 3.5 × 3.5 × 10 = 384.65 cm^3

Answer 2

Answer:

$\pi \: {r}^{2} h = \frac{22}{7} \times {3.5}^{2} \times 10 {cm}^{3} \\ = \frac{22}{7} \times 12.25 \times 10 {cm}^{3} \\ = 385 {cm}^{3}$
