GCSE Maths Practice: volume

Question 3 of 10

This question asks you to calculate the volume of a cylinder. Cylinders have circular bases and straight sides.

‹ ›

\( \begin{array}{l}\text{Find the volume of a cylinder with radius 3 cm and height 5 cm. Use π ≈ 3.14.}\end{array} \)

Choose one option:

Use formula V = π × r^2 × h. Square radius first, then multiply by π and height.

Volume of a cylinder is calculated as V = π × r^2 × h, where r is radius, h is height. For radius 3 cm and height 5 cm: V = 3.14 × 3^2 × 5 = 3.14 × 9 × 5 = 141.3 cm^3. Understanding cylinder volume is useful in real-life situations like cans, pipes, and tanks. Visualising the cylinder as stacked circles can help. Remember to square the radius before multiplying by π and height. Approximate π as 3.14 unless otherwise instructed. Practice with different radii and heights to see how the volume changes.
