Answer:
Substitute the known circumference into the formula C = πd. Divide by π to find the diameter. Then divide the diameter in half to find the radius. Substitute the radius into the area formula, A = πr2. Square the radius and multiply by π to get the area.
Step-by-step explanation:
These are overall steps for finding the area of circle whose circumference is given.
What is Circle?
A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”.
Here, Circumference of circle is given C units
2πr = C
r = C / 2π
Now, Area of circle = πr²
A = π X (C/2π)²
A = π X C²/4π²
A = C²/4π
Thus, these are overall steps for finding the area of circle whose circumference is given.
