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

= 2.272

= 2.72 m.............................

so it should have a height of 2.72 m inorder to hold 350.0m^3

ANSWER IS

2.72 m

....

hope you understood..please mesage if you have any doubts,,,thank you
