Question

Find the volume of the cylinder whose radius is
0.7cm and height = 1.4 cm. plese answer in notebook
​

Answer 1

Answer:

1.156cm³ is the volume

Answer 2

The volume of a cylinder = 2.156 $cm^{3}$

Step-by-step explanation:

Given,

The base radius of a cylinder (r) = 0.7 cm and

The height of a cylinder (h) = 1.4 cm

To find, the volume of a cylinder = ?

We know that,

The volume of a cylinder = $\pi r^2h$

$= \dfrac{22}{7} \times 0.7^2 \times 1.4 cm^{3}$

$= \dfrac{22}{7} \times 0.7 \times 0.7\times 1.4 cm^{3}$

= 22 × 0.7 × 0.7 × 0.2 $cm^{3}$

= 15.4 × 0.14 $cm^{3}$

= 2.156 $cm^{3}$

∴ The volume of a cylinder = 2.156 $cm^{3}$
