A cylinder is full at 471 cm3 and has a radius of 5 cm. It currently contains 314 cm3 of water.

What will the difference in the height of the water be when the cylinder is full?

Use 3.14 to approximate pi.

anonymous · Answer

you need the volume formula for a cylinder

anonymous · Answer

(3.14)r^2 H
r = radius
h = height

anonymous · Answer

set up the equation for the water first.
314 = (3.14) * (5)^2 * H

iyuko · Answer

Okay but how to find height?

anonymous · Answer

solving the equation listed above. 
If you notice that its the only variable in the problem.
isolate it by dividing both sides by 3.14
then divide by 5^2

anonymous · Answer

then using the same equation set up the equation for full cylinder and get the height of that.
H(1) of the first equation minus H(2) of the second equation.
