A cylindrical water tank has a radius of 7m. About how high must it be filled to hold 350.0m^3? Please round to two decimal places.
volume of cylinder = π r^2 h
where r = radius ,h = height ,π = 3.14
to hold 350.0m^3 volume should be 350.0m^3
thus substituting in equation
350.0m^3 = π 7^2 h
h= 350.0 / 49 π
= 350 /154
= 2.72 m.............................
so it should have a height of 2.72 m inorder to hold 350.0m^3
hope you understood..please mesage if you have any doubts,,,thank you
