GCSE Maths Practice: surface-area

Question 1 of 10

This question identifies which parts contribute to the total surface area of a cylinder.

›

\( \begin{array}{l}\text{Which parts are included when finding the total surface area of a cylinder?}\end{array} \)

Select all correct options:

\( \text{Top circular face} \) \( \text{Bottom circular face} \) \( \text{Curved surface} \) \( \text{Volume of the cylinder} \)

Include both bases and curved side for surface area; ignore volume.

To find a cylinder's total surface area, include the top and bottom circular faces and the curved side. Volume is different and measures space inside. Example: radius 3 cm, height 10 cm → curved surface = 2πrh = 60π, circular bases = 2πr² = 18π, total surface area = 78π. Understanding which parts contribute prevents errors and is essential for real-world applications like wrapping or coating cylinders.
