Find the volume and the surface area of the open hollow cylinder

Answer 1

To find the volume of the open hollow cylinder, we need to know the radius of the outer and inner circles, as well as the height of the cylinder. Let's denote the radius of the outer circle as R, the radius of the inner circle as r, and the height as h.

The volume of a hollow cylinder is given by the formula V = πh(R^2 - r^2).

The surface area of the open hollow cylinder is given by the formula A = 2πhR + π(R^2 - r^2).

Note that the formula for surface area includes the curved surface area (2πhR) and the difference in areas of the two circles (π(R^2 - r^2)).

Therefore, to find the volume and surface area of the open hollow cylinder, we need to know the values of R, r, and h.
