CORRECT QUESTION.
The height of the right circular cylinder is twice
it's radius of the base. if it's height be 6 times
radius of the base then the volume of cylinder
will be 539cm^3. assume π = 22/7. find height of the the cylinder is.
TO FIND HEIGHT OF THE CYLINDER.
EXPLANATION.
Let the radius of the cylinder = r
Let the height of the cylinder = 2r
if it's height be 6 times of it's radius
Therefore,
New height of the cylinder = 6r
According to the question,
πr^2 X 6r - πr^2 X 2r = 539
4πr^3 = 539
r^3 = (7/2)^3
r = 7/2
Therefore,
height of the cylinder = 2r = 2 X 7/2 = 7cm
