Question

A rectangle is of length 8 inches, breath 11 inches and thickness 2 inches. when it is shaped to a cylindrical rod with the diameter is 10m. what is the height of the cylinder?​

Answer 1

Answer:

For Rectangle:-

We have given length of rectangle= 8 inches

Breadth of rectangle= 11 inches

Thickness of rectangle= 2 inches

For Cylinder:-

We have given diameter= 10m

Therefore, Radius= d/2

= 10m/2

= 5m

Now, we have given dimensions of rectangle in inches and cylinder in meters.

With the given dimensions of rectangle, Volume(in m³)=8×11×2×(0.0254)³

=0.00288 m³ =cylinder's volume

Let cylinder's height=h

Radius is=5 m

Then by formula πr²h,

(22/7)×(25)×h= 0.00288

(550/7)×h=0.00288

h=0.00288×7/550

h=0.0216/550 m

Therefore, height of cylinder= 0.0216/550 m or 3.66545455e-5
