Answer 2

The volume of a cylinder = 1540 $cm^{3}$

Step-by-step explanation:

Given,

The curved surface area of a cylinder = 440 $cm^2$ and

The base circumference of cylinder = 44 cm

To find, the volume of a cylinder = ?

Let the radius of the cylinder = r

∴ The base circumference of cylinder = $2\pi r$

⇒ $2\times \dfrac{22}{7}\times r=44$

⇒  r = $\dfrac{44\times 7}{44}$

⇒  r = 7 cm

The curved surface area of a cylinder = $(2\pi r)h$

⇒ $(2\pi r)h$ = 440

⇒ 44(h) = 440

⇒ h = 10 cm

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

= $\dfrac{22}{7}\times 7^2\times 10$

= $22\times 7\times 10$

= 1540 $cm^{3}$

∴ The volume of a cylinder = 1540 $cm^{3}$
