**What is a Circle & What is the Radius of Circle?**

A circle is a specific type of ellipse in mathematics or geometry in which the eccentricity is zero and the 2 foci are coinciding. A circle is often referred to as the locus of points drawn equidistant from the center of the circle. The radius of circle is the distance from its center to its outside line. A diameter is a line that splits a circle into 2 equal pieces and is equal to twice the radius. The radius of any given circle is denoted using the letter ‘r’ whereas the diameter of any given circle is denoted by the letter D.

A circle is a fundamental 2D form that is measured by its radius. The rings split the aircraft into two sections: inner and outside. It is comparable to a line segment. Assume that the line segment is twisted around until its ends meet. Arrange the loop such that it is perfectly round.

**What is Radius?**

A circle is a 2-dimensional shape with an area and a perimeter. The circumference of a circle is also known as its perimeter, and it is the distance around the circle. In a 2D plane, the area of a circle is the region surrounded by it.

A radius is the distance between the center of a circular item and its outermost edge or border. A radius is a measurement not just of a circle, but also of a sphere, semi-sphere, cone with a circular base, and cylinder with circular bases.

A circle is defined as the locus of a point traveling in a plane so that its distance from a fixed point is always fixed. The fixed point is referred to as the circle’s center, and the distance between any point on the circle and its center is referred to as the radius of a circle.

We can find the radius of any given circle by using the formula Radius (r) = Diameter (d)/2.

**Examples –**

You have been given a wheel with the length of its diameter which measures 10 cm and you need to know the radius of the wheel. Let’s know how to calculate the radius of the wheel.

- As we have already discussed in the article above, we can calculate the radius of the wheel using the formula Radius = Diameter/2.
- Putting the values in the formula, we get radius (r) = 10 cm/2 = 5 cm
