About the Area of a Circle

For this example, see the image shown below. We know how to find the area of a circle here. The area for a circle is calculated by calculating the radius. If you have the measurement of the diameter of the circle then just do the diameter of the circle / 2. You will now be able to get its measurement in the radius of a circle. Once you’ve set the radius or diameter of the circle or circled it off on blueprints and schematics, the calculation is simple. Or you can insert the values in the above-mentioned formulae or you can use the Area of a Circle Calculator. Keep in mind that the diameter is the largest measurement you can get from a circle by hand. The area of the circle can be found by a formula. The formula to find area A of the circle is as follows − A = π r².

A based formula is found here for finding the area of a circle. In the above, we are given a radius of circle as 50. Now we just need to know what the area of a circle is based on the radius of the circle we have. Now we will use the formula. Our formula is A= π r². If we put the value of r in the formula, we have now, A = π 50². π 50 × 50 Now if we replace π in the formula, this gives us A = 3.14159 × 2500. This means that the area of a radius of 50 of a circle should be 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 $31, 415.9 {cm}^{2}$ .
