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\(r\) × \(h\)).

Radius of the hemisphere = 14 cm ÷ 2 = 7 cm Height of the cylinder = 13 cm - 7 cm ... 15.5 cm - 3.5 cm = 12 cm The total ...
