The height of a right cylinder is 3 times the radius of the base. the volume of the cylinder is 24 cubic units what is the height of the cylinder

Put the given information into the formula and solve for the variable of interest.
.. V = π*r^2*h
.. 24 = π*(h/3)^2*h
.. 24 = π/9*h^3
.. 9*24/π = h^3
.. ∛(216/π) = h
.. h = (6/π)√(π^2) ≈ 4.097 . . . . units

The height of the cylinder is about 4.097 units.

Ithink it's the first one ( let me know if it right)
