Find the diameter of a circle with area of 380.1 m²

Radius = 11

Circumference = 69.115

Diameter = 22

Step-by-step 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.    

Diameter=22m

Step-by-step 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

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
