Answer 2

Answer:

The weight of the iron cylinder is 50.24 kg.

Step-by-step explanation:

It is given that the height of the cylinder is 20 cm, and the radius of the base is 10 cm.

The weight of the cylinder can be found by calculating the volume of the cylinder. The formula for the volume of the cylinder is given as follows,

         $V=\pi r^2h$

Now substitute the values to find the volume.

      h = 20 cm

       r = 10 cm

       $\pi=3.14$

 ∴    $V=3.14\times 10^2\times 20$

       $V= 6280\ cm^3$

1 cubic centimeter of iron is 8 grams. Then the weight of the cylinder = $6280\times 8= 50240\ g$

We know that 1000 g = 1 kg

∴ Weight = $\dfrac{50240}{1000} = 50.24\ kg$
