GCSE Maths Practice: circle-properties

Question 10 of 10

This question tests multi-step diameter and radius understanding.

‹

\( \begin{array}{l}\text{A circle has radius 5 cm.}\\ \text{Find its diameter.}\end{array} \)

Choose one option:

Multiply the radius by 2 to find the diameter.

Calculating the diameter from a given radius reinforces understanding of circle properties. Higher difficulty arises when students must apply formulas within contextual problems or convert units. Practising with multiple examples strengthens precision and familiarity with geometric formulas, preparing students for circumference, area, and composite circle problems.
