Question

a solid iron rod has a cylindrical shape h=11 cm and base diameter 7 cm. find volume of 50 rods

Answer 1

this is answer of Volume of Cylinder

Answer 2

Answer: The volume of 50 rod is 21,155.75 cm³

Step-by-step explanation:

Since, The volume of a cylinder is,

$V=\pi r^2h$

Where r is the radius of the cylinder and h is the height.

Here, the diameter of one cylinder = 7 cm,

⇒ Radius of one cylinder, r = 7/2 = 3.5 cm

And, the height of a cylinder, h = 11 cm,

⇒ The volume of 1 cylinder,

$V=\pi (3.5)^2(11)=3.14\times 12.25\times 11 = 423.115\text{ cube cm}$

⇒ The volume of 50 cylinder = 50 × 423.115

= 21,155.75 cube cm
