## Step 1: How to Find the Area of a Circle?

Finding the area of a circle might be daunting to some people, so in this instructable I will show you how.

## Step 2: Step 1.

The most important part about learning how to find the area of a circle is to know the formula.

The formula is R2xPi. Or if you want to see how it looks if you write it by hand, look to the above image.

## Step 3: Step 2.

What is Pi?

Pi is a infinitely expanding number, but you will probably only need the first 3 numbers. The numbers you will use from Pi to find the area of a circle are 3.14

## Step 4: Step 3.

In the formula, it states that to find the area of a circle you must use Pi x R2.

R2 stands for the radius times the radius. In this instructable I am going to assume that the circles radius is 4, which means that R2=4x4=16.

## Step 5: Step 4.

This is the final step.

To finally find the area of the circle that I am using as an example you would use this formula, A=R2 x 3.14

If you do the math, this equals 50.24

## Step 6: Conclusion

I hope that this instructable helped you learn how to find the area of a circle.
