Question

How to find area from circumference.(General explanation of how to calculate the area given the circumference of a circle).

Answer 1

The area of a circle can be calculated using this formula:

`A=\pi r^2`

Where "r" is the radius of the circle.

The formula for calculating the circumference of a circle is:

`C=2\pi r`

Where "r" is the radius of the circle.

If you need to find the area of a circle and you don't know its radius but you know the circumference, you can substitute the value of the circumference into the formula for calculating the circumference of a circle, and then solve for "r":

`r=(C)/(2\pi)`

Once you know the radius, you can substitute it into the formula for calculating the area of a circle and find its area.

Hence, the answer is:

- Substitute the value of the circumference into the formula for calculating the circumference of a circle, and solve for the radius "r".

- Substitute the value of the radius "r" into the formula for calculating the area of a circle.
