Question

4. An iron block is in the form of a cylinder of diameter 0.5 m and length 3.5m This block is to be converted into a cylindrical roller with diameter 125cm. Find the length of the roller.​

Answer 1

Answer:

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=

×3.5

= l \times 0.25 \times 0.25=l×0.25×0.25

= \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=

7×2×2×0.25×0.25

22×0.5×0.5×3.5

m=11m

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