Or, the radius of the circle. The distance between the center of the circle and any point on the circumference. A radius can be represented by using a small letter r, and it is the distance from the center of a circle to a point on its circumference. Sometimes, you will see a capital R (R for radius), which is an abbreviation for radius.

What do the word r mean in math?

That’s right, the r in an equation is the root. It’s the solution to the equation. The two main kinds of roots are roots of polynomials and roots of functions. A polynomial is a function that can be represented by an algebraic equation. Roots of polynomials are easier to find, because they can be found using the methods of elementary algebra. Roots of functions (also known as radical expressions) are harder to find.
