Area of a Circle GCSE Maths
Area of a circle questions are common in GCSE Maths. The key is to identify the radius correctly and substitute it into the formula.
Key Method
If the radius is 5 cm, the area is π × 5² = 25π cm². On a calculator, this is approximately 78.5 cm².
Exam tip: If the question gives the diameter, divide it by 2 first to find the radius.
Common mistake: Students often square the diameter instead of the radius.
