Question

A flour container is 25cm tall and has a diameter of 20cm. It is filled to 3cm from the top. What volume of flour does it contain?
HOw do i solve this please explain!

Answer 1

You need the formula for the volume of a cylinder.
V = (pi)(r^2)h, where
V = volume of cylinder,
pi = famous constant, 3.14159...
r = radius of base
h = height of cylinder

In this case you have the diameter of the base is 20 cm.
d = 20 cm
r =d/2 = (20 cm)/2 = 10 cm
h = 25 cm - 3 cm = 22 cm (you are looking for the volume of the flour, not the total volume of the cylinder.

Now insert r = 10 cm and h = 22 cm into
V = (pi)(r^2)h,
and calculate the volume.
