## Area of a Circle – Proof | Geometry | Maths | Tutorial

You may not know this but there is no way of calculating the area of a circle exactly. The area of a circle is calculated by splitting the circle into many right-angle triangles and then calculating the area of these triangles. As you know triangles have straight lines and circles are curved therefore Continue reading “Area of a Circle – Proof | Geometry | Maths | Tutorial”

## Emma’s Dilemma – Permutations with Unique & Repeating Letters | Maths | Tutorial

In this scenario we look at two names EMMA and LUCY, we want to find out all the possible arrangements the letters of their name can be used to make this is known as permutations. We will also learn to use a formula that will help calculate how many different combinations there are without having to write them down manually this is especially useful if there are 100’s of possibilities.
