Question

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.
_____cm

Answer 1

The correct answer for the question that is being presented above is this one: "2 cm."

The formula of the volume is:
Volume = pi * r^2 * h
471 = 3.14 * 5^2 * h
471 = 78.5h
h = 6 cm

Volume = pi * r^2 * h
314 = 3.14 * 5^2 * h
314 = 78.5h
h = 4 cm

So the difference is 6 cm - 4 cm = 2 cm.
