About the Area of a Circle

To understand this example, see the image given below. Here, we understand how to find the area of a circle. To calculate the Area of a circle, it is necessary to measure the radius. And if you have the measurement of the diameter of the circle then you have to do the diameter of the circle / 2. Now you will get the measurement of the radius of a circle. Once you have determined the circle’s radius or diameter, or if you know it from blueprints and schematics, the calculation is simple. enter the values into the preceding formulae, or use our Area of a Circle Calculator. Remember that the diameter is the maximum measurement you may obtain from a circle if you are measuring it by hand. There is a formula to find the area of a circle. The formula to find the area (A) of a circle is given as follows – A = π r²

Here we find the area of a circle based on the formula. We are given a circle, and the radius of the circle is 50. Now we have to find the area of the circle based on the value of the radius of the circle. Now we will use the formula. Our formula is A = π r2. Now if we put the value of r in the formula, then A = π 50². A = π 50 * 50 Now if we write the value of π in the formula, then, it will be A = 3.14159 * 2500. So the area of a circle with a radius of 50 is approximately 7853.975 square cm.

Area of a circle calculation formula

How do we calculate the area of a circle here? This is about to understand. First of all we will need the formula to calculate the area of a circle. The formula we have given below. The formula for finding the area ( $A$ ) of a circle is given by -

$� = � �^{2}$

Area of a circle calculation example

Now, we will use the formula given above here. And based on this formula we will calculate the area of the circle. If the radius (r) is given as 100 cm, you can substitute this value into the formula -

$� = � \times 10 0^{2}$

Now, calculate the area

$� = 3.14159 \times 10, 000$

$� \approx 31, 415.9$

So, the area of a circle with a radius of 100 is approximately $31, 415.9 {cm}^{2}$ .
