Circles

In this lesson, we will investigate how to calculate the circumference of a circle. We will explore the formula used for this calculation, and practise finding the circumference from a given radius or diameter.

In this lesson, we will find the diameter or radius of a circle when given the circumference. This lesson will involve rearranging the formula for the circumference of a circle.

In this lesson, we will investigate how to find the area of a circle. We will practise finding the area of circles and semicircles when given either the radius or the diameter.

In this lesson, we will learn how to find the radius or diameter of a circle when given the area. This lesson will involve rearranging the formula for the area of a circle.
