Question

Height of cylinder=0.5, Radius=0.4 find the volume​

Answer 1

Answer:

πr^2h

3.14 x 0.5 x 0.5 x 0.4

= 0.314 unit square

Answer 2

Given :-

Height of cylinder = h = 0.5

Radius = r = 0.4

To find :-

Volume of cylinder = !?

$\underline\mathtt\blue{formula:}$

$\underline\mathtt\green{volume \: of \: cylinder:} \: = \pi \: r ^{2} \: h$

$→ Volume \: of \: cylinder = \frac{22}{7} \times (0.4 )^{2} \times 0.5 \\ vol.of \: cylinder = \frac{22}{7} \times 0.4 \times 0.4 \times 0.5 \\ = \frac{22}{7} \times 4 \times {10}^{ - 1} \times 4 \times {10}^{ - 1} \times 5 \times {10}^{ - 1} \\ \frac{22}{7} \times 16 \times 5 \times {10}^{ - 3} \\ 3.14 \times 80 \times {10}^{ - 3} \\ 3.14 \times 8 \times {10}^{1} \times {10}^{ - 3} \\ 3.14 \times 8 \times {10}^{ - 2} \\ = 25.12 \times {10}^{ - 2} \\ 0.25$
