GCSE Maths Practice: volume

Question 7 of 10

This question asks for the formula to calculate the volume of a cone.

‹ ›

\( \begin{array}{l}\text{Which formula gives the volume of a cone?}\end{array} \)

Choose one option:

Square the radius, multiply by height, divide by 3, include π.

Volume of a cone = 1/3 × π × r^2 × h, where r is the radius and h is the height. The formula comes from the relationship between a cone and a cylinder with the same base and height. For example, a cone with radius 3 cm and height 6 cm: V = 1/3 × π × 9 × 6 = 18π cm^3. Using this formula is crucial in real-life contexts like ice cream cones, funnels, and storage containers. Always square the radius first, multiply by height, then divide by 3, and include π. Practice applying the formula for different cones.
