Answer:

Diameter=22m

Explanation:

A=pi×r²=pi×d²/4, where r is the radius, and d=2r is the diameter.

d²=4×A/pi=4×380.1/3.14=484m²=22²m².

Thus d=22m

Answer:

Radius = 11

Circumference = 69.115

Diameter = 22

Explanation:

First you have to take the area and solve for the circumference, after find the radius. Once you have that you multiply that by 2 since the radius is half of the diameter.
