Question

the radius of wirl decreased to one-third.its volume remains the same length will increase
​

Answer 1

Step-by-step explanation:

Volume = area (CS) * length

Area (CS) = πr²

If r -> r/3,

Area' = πr²/9

Since the volume remains same,

Volume = Area' * length'

Area * length = (Area/9) * length'

length' = 9 * length
