Area of a circle with a diameter of 63

That is a question about circle area.

To calculate the area of a circle, we multiplicate the constant pi () by the radius (of the circle) squared. The expression represents that is below:

In our problem, we don't know what is the circle raius, but we know the diameter. In a circle, the diameter is equal the double radius.

So, to know the radius of our circle, we divided the diameter by 2. Consequently, the raius of our circle is .

Now, we should use the expression and we will find the area:

Therefore, the area of a circle with a diameter of 63 is approximately 3115.665.

I hope I've helped. :D
