The heights and diameters of these cylinders A and B are interchanged. We know that,
Volume of cylinder = πr2h
If measures of r and h are same, then the cylinder with greater radius will have greater area.
Radius of cylinder A = (7/2) cm
Radius of cylinder B = (14/2) cm
= 7 cm
As the radius of cylinder B is greater, therefore, the volume of cylinder B will be greater.
Let us verify it by calculating the volume of both the cylinders.
Volume of cylinder A
Thus, the surface area of cylinder B is also greater than the surface area of cylinder A.
