The volume of a clyinder is defined by the formula V=pie r2 h. if intially have a clyinder with a volume of 10m3, FIND THE VOLUME OF THE CLYINDER IF THE height is doubled

Question

wolf1728 · Answer

The volume would be doubled if the height is doubled.

wolf1728 · Answer

V=pi•r²•h
The height has no exponent on it so a change in height is strictly linear.
If you would double the radius the volume would increase four times.  
The reason?
In the formula the radius is squared so doubling r² produces a change of of four.
2² = 4

And to answer the question, the volume becomes 20 m³ if the height is doubled.
