Introduction to Circle Area

The area of a circle measures the space inside the circle. Finding circle area is essential for many applications from pizza sizes to circular gardens to satellite dish design.

The formula for circle area uses π (pi) and the radius squared. Understanding why we square the radius helps you remember the formula and avoid common mistakes.

In this lesson, you'll learn to calculate the area of circles using the formula A = πr² and solve related problems.
