You dived the area by the circumference of the circle.
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
Area = (Circumference squared)/4 pi Circumference = 2 sqrt(Area times pi)
The area of a circle with circumference 9.42in is: about 7.061 square inches.
To find the area of a circle with a given circumference, you can use the formula A = (C^2) / (4π), where A is the area and C is the circumference. Plugging in the values, we get A = (42^2) / (4π) = 1764 / (4π) ≈ 140.72 square units.
