Question

the circumference of the base of a right circular cylinder is 528 cm and its height is 2 metre what is the volume of the cylinder​

Answer 1

The circumference of the base of a right circular cylinder is 528 cm and its height is 2 metre then the volume of the cylinder is 4.43 m³.

Step-by-step explanation:

The height of the cylinder, h = 2 m  

Let the radius of the base of the cylinder is “r”.

The circumference of the base of the right circular cylinder = 528 cm

⇒ 2πr = 528

⇒ 2 * (22/7) * r = 528

⇒ r = [528 * 7] / [2 * 22]

⇒ r = 84 cm ≈ 0.84 m

Thus,

The volume of the cylinder is given by,

= πr²h

= (22/7) * (0.84)² * 2

= 22 * 0.12 * 0.84 * 2

= 4.43 m³

Answer 2

The volume of the cylinder​ is $4435200 cm^{3}$ or$4.435200 m^{3}$

Step-by-step explanation:

Given,

The circumference of the base of a right circular cylinder = 528 cm and

height = 2 metre = 200 cm

Let  the radius of base of a right circular cylinder = r

To find, the volume of the cylinder​ = ?

We know that,

The circumference of the base of a right circular cylinder = $2\pi r$

⇒$2\times \dfrac{22}{7} \times r=528$

⇒$r=\dfrac{528\times 7}{44} =12\times 7=84cm$

∴ The volume of the cylinder​ = $\pi r^{2} h$

= $\dfrac{22}{7} \times 84 \times 84 \times 200$

$= 22 \times 12 \times 84 \times 200=264\times 16800 cm^{3}$

$=4435200cm^{3}$

=4.435200m^{3}

Hence, the volume of the cylinder​ is $4435200 cm^{3}$ or $4.435200 m^{3}$
