GCSE Maths Practice: 3d-shapes-and-nets

Question 10 of 10

Identify which 3D shapes have curved surfaces.

‹

\( \begin{array}{l}\text{Which of these 3D shapes have curved surfaces?}\end{array} \)

Select all correct options:

Look for smooth surfaces; flat faces do not count as curved.

Curved surfaces in 3D shapes are surfaces that are not flat. A sphere is entirely curved, a cylinder has a curved lateral surface, and a cone has a curved surface connecting the base to the apex. Recognizing which shapes have curved surfaces is important for understanding geometry, calculating surface areas, and distinguishing between polyhedra and solids of revolution. Practice identifying curved versus flat faces on 3D models or diagrams. This helps in solving real-life geometry problems and improves spatial visualization skills.
