is to be rolled into the form of a bar having square section of side 25 cm find the length of the bar

Answer 1

Hey mate!

Here's your answer!!
_____________________

We know that,

Volume of cylinder = Volume of cuboid bar

➡ πr²h = lbh

$= \frac{22}{7} \times \frac{0.5}{2} \times \frac{0.5}{2} \times 3.5$

$= l \times 0.25 \times 0.25$

$= \frac{22 \times 0.5 \times 0.5 \times 3.5}{7 \times 2 \times 2 \times 0.25 \times 0.25}m = 11 \: m$

Therefore, the length of the cuboid bar is 11 m.
