GCSE Maths Practice: surface-area

Question 2 of 10

This question identifies 3D shapes that include curved surfaces in their surface area.

‹ ›

\( \begin{array}{l}\text{Which shapes have curved surfaces as part of their surface area?}\end{array} \)

Select all correct options:

\( \text{Sphere} \) \( \text{Cylinder} \) \( \text{Cuboid} \) \( \text{Cone} \)

Look for rounded surfaces; flat faces do not contribute to curved surface area.

Curved surfaces appear on spheres, cylinders, and cones. Cuboids have only flat faces. Recognizing curved versus flat surfaces is essential when calculating surface area. For example, cylinders and cones require formulas involving radius and slant height. Spheres require 4πr². Practice with multiple 3D shapes to reinforce identifying which surfaces are curved.
