How to Find Diameter of a Circle?

If the radius, circumference, or area of a circle are specified, the diameter could be computed. To determine the diameter of a circle, follow the steps below:

Step 1: Determine the parameters given in the question i.e. radius, area, or circumference.

Step 2: Choose the proper formula from the three mentioned in the previous section.

Step 3: Put the value of the given parameter in the suitable formula and simplify the same to get the required answer.

As an example, let us use the above-mentioned formula to calculate the diameter. Consider the following example.

Example: Find the diameter of a circle with a radius of 10 units.

Solution:

Given: Radius of Circle = 10 units

Diameter of Circle = 2 × Radius

D = 2 × 10 = 20 units

Thus, the diameter of the circle is 20 units.

Diameter of a Circle

Diameter of a Circle is a line that travels through the centre and intersects the circumference at opposing ends. In other terms, the diameter of a circle is the line that goes through its centre and splits it into two equal sections. A circle’s diameter is any straight line segment that travels through the centre of the circle and has endpoints on the circle’s perimeter. The circle’s diameter is referred to as its longest chord.
