Formula - How to calculate the **diameter** **of** **a** **circle** from the **area**. π is approximately 3.1415926535. **Diameter** = 2 x (√(**Area** ÷ π)) Example. A **circle** has an **area** **of** 10. Let’s see python program to calculate the **area** and circumference **of a circle**. Firstly, we will take input from the user using the input () function for radius and store it in a variable. We can use constant to store the value of ‘pi’. Now, we will calculate the **area of a circle** by using the formula **area** = PI * r * r.

The **diameter** **of** **a** **circle** is the distance across the **circle**. In more exact words, it is the segment of a straight line that passes through the center of the **circle** and ends where it touches two points on the **circle**. The **diameter** equals twice the radius of the **circle**. Any **diameter** divides the **circle** (or rather the disk) into two equal halves.

The **area** **of** **a** **circle** is defined as space or the region it occupies in a two-dimensional plane. It is denoted by A and measured in the square unit, such as m 2, cm 2, etc. Formula: The **area** **of** the **circle** can be determined by the given formula. A = πr2 π r 2. where r = radius of a **circle**. d = **diameter** **of** **a** **circle**. The **area** **of** **a** **circle** can be found by multiplying pi ( π = 3.14) by the square of the radius If a **circle** has a radius of 4, its **area** is 3.14*4*4=50.24 If you know the **diameter**, the radius is 1/2 as large.
