The **radius** of a regular **hexagon**, also called its circumradius, is the distance from its center to its vertexes, or points. Regular **hexagons** are polygons with six equal sides. The **radius** length allows the **hexagon** to be divided into six equal triangles that help in calculating the area of the **hexagon**.

Keeping this in consideration, How do we find the radius of a circle?

To calculate the **radius of a circle** by using the circumference, take the circumference of the **circle** and divide it by 2 times π. For a **circle** with a circumference of 15, you would divide 15 by 2 times 3.14 and round the decimal point to your answer of approximately 2.39.

Also know, Is the radius of a hexagon equal to the side?

**Radius equals side**length

In a regular **hexagon**, the **radius equals** the **side** length. That is, a line from the center to any vertex will have the same length as any **side**.

**How do you find area?**

To **find the area** of a rectangle multiply its height by its width. For a square you only need to **find** the length of one of the sides (as each side is the same length) and then multiply this by itself to **find the area**. This is the same as saying length^{2} or length squared.

**What is Apothem of a polygon?**

We know that **area** of **circle** = π*r^{2}, where r is the radius of given **circle**. We also know that radius of Circumcircle of an **equilateral triangle** = (side of the **equilateral triangle**)/ √3. Therefore, **area** = π*r^{2} = π*a^{2}/3.

**What is the Apothem of an equilateral triangle?**

The **apothem** is the distance from the center of the polygon to the midpoint of a side. In this case we have a **triangle** so the **Apothem** is the distance from the center of the **triangle** to the midpoint of the side of the **triangle**. The **Apothem** is perpendicular to the side of the **triangle**, and creates a right angle.

**What is the function for the area of an equilateral triangle?**

The **area of an equilateral triangle** is the height of the **triangle** multiplied by half the base. The base is the length of one side, x. The height is found by bisecting the angle at the top and drawing a line to the base.
