Question

A cylinder of base radius 4.9cm and height 12cm find the volume

Answer 1

Answer:

volume = 905.52

Step-by-step explanation:

v=

$\pi \times r \times r \times h$

v = 905.52

Answer 2

The volume of a cylinder = 905.52 $cm^{3}$

Step-by-step explanation:

Given,

The base radius of a cylinder (r) = 4.9 cm and

The height of a cylinder (h) = 12 cm

To find, the volume of a cylinder = ?

We know that,

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

= $\dfrac{22}{7} \times 4.9^2 \times 12 cm^{3}$

= $\dfrac{22}{7} \times 4.9 \times 4.9\times 12 cm^{3}$

= 22 × 0.7 × 4.9 × 12 $cm^{3}$

= 15.4 × 58.8 $cm^{3}$

= 905.52 $cm^{3}$

∴ The volume of a cylinder = 905.52 $cm^{3}$
