Find the diameter of a circle with an area of 380.13m^2

22

Step-by-step explanation:

Divide the area (in square units) by Pi (approximately 3.14159).

Example: 380.13/3.14 = 121.06

Then square the answer.

121.06 squared = 11.0

That answer is the radius, double that to get the diameter.

11.0 * 2 = 22
