GCSE Maths Practice: volume

Question 10 of 10

This question asks which solids use π in their volume formula.

‹

\( \begin{array}{l}\text{Which solids use π in their volume formula?}\end{array} \)

Select all correct options:

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

Check if the solid contains circular faces; then include π in volume calculation.

Solids that include circles in their base or shape (sphere, cylinder, cone) require π in their volume formula. A cuboid does not involve π because it has only rectangular faces. Examples: Cylinder: V = π r^2 h; Cone: V = 1/3 π r^2 h; Sphere: V = 4/3 π r^3. Understanding which solids involve π helps in solving calculations accurately. Practice identifying circular components and applying formulas correctly.
