To calculate the surface area of a cylinder: Work out the area of the two circular faces (2 × π\(r\)²). Work out the curved surface area, this is the rectangular face (2π\(r\) × \(h\)).

pi r^2 h\) Calculate the volume of the cylinder. The measurement shown is the diameter of the circular face, so the radius is 3.5 cm. Substituting the values \(h = 16~cm\) and \(r = 3.5~cm\) into ...
