Title: How to Calculate the Area of a Circle

Calculating the area of a circle can be done using a simple formula: [ A = \pi r^2 ] Where ( A ) is the area and ( r ) is the radius. In South Africa, this concept is typically covered in Grade 11 math, specifically within the topic of circle geometry. To find the area, simply square the radius and multiply it by ( \pi ). Understanding this fundamental concept is crucial for further studies in mathematics and various real-life applications.
