A rope is wound 50 times round a cylinder of radius 25cm how long is the rope [use the value 3.14 for pi]

Answer 1

C = πd

d = 2r

In your case:

C = 50 * π * 2r

Insert values and calculate for C

Answer 8

A rope is wound 50 times round a cylinder of rzdius 25cm .What is the approximate length of the rope? Use the value of 3.14 for the

Answer 9

98625

Answer 10

To find the length of the rope wound around the cylinder, we need to find the circumference of the cylinder and then multiply it by the number of times it is wound around.

The circumference of the cylinder = 2πr, where r = radius of the cylinder

Circumference of the cylinder = 2 × 3.14 × 25 cm = 157 cm

Total length of rope = 157 cm × 50 times = 7850 cm

Therefore, the approximate length of the rope is 7850 cm or 78.5 meters (rounded to one decimal place).

Answer 11

7850

Answer 12

Yes, that's correct! The approximate length of the rope is 7850 cm.
