The volume V of such a hollow cylinder is given by
the formula V = π (R^2 −r ^2 )h . Find the volume of
such a cylinder in cm3, given that its external
radius, thickness (R - r) and height are 7.4cm,
1.3cm and 12 cm respectively.
How can I type this in the matlab???
thanx

here you must be smart.
(R^2- r^2)=(R+r)(R-r)= V/3.14
That show you that both sum and difference will have effect on the volume.
You must decide one of the radius lines and then you can solve the problem for that chosen value.

I am not sure what matlab is but the answers are:
pi*7.4^3
pi*1.3^3
pi*12^3.
Since the measures are given in cm, the volumes will be in cm^3
