GCSE Maths Practice: circle-properties

Question 7 of 10

This question teaches the formula for the area of a circle in terms of radius.

‹ ›

\( \begin{array}{l}\text{Write the formula for the area of a circle in terms of the radius } r.\end{array} \)

Choose one option:

Multiply π by the square of the radius to find the area.

The area of a circle is calculated using the formula πr², where r is the radius. This represents the two-dimensional space enclosed by the circle. Students should practise applying this formula to calculate areas given different radii. Understanding this formula is fundamental for geometry problems, real-life applications, and exam questions. Visualising the radius and how squaring it scales the area helps in comprehension. Mastery of the area formula prepares students for more advanced geometry topics and practical calculations.
