Answer: x=8/81
Step-by-step explanation 
3x divide by 3 
8/27 divide by 3
it becomes x=8/27 divide by 3 and 3 becomes 1/3

Answer:
the volume is 

Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a cylinder.
Given data
Volume v =  ?
Radius r =  r in
Height h=   2r in
We are expected to solve for the volume of a cylinder, given the above data we can substitute it in the formula for volume of a cylinder to obtain our result
 we know that the expression for the volume of a cylinder is 


Hence the volume in terms of the radius is
