Answer:

14 meters

Step-by-step explanation:

The area of a circle can be found with the formula: πr^2

We can set up an equation to find the radius, and use that to find diameter.

πr^2=49π

Divide both sides by π.

r^2=49

r= [tex]\sqrt{49\\}[/tex]

r=7

Radius is half of diameter, which means 2r=d

d=2(7)

d=14

Answer:

Step-by-step explanation:

hello :

The area is :A = πr²  r : ridus    the diameter is : d=2r

calculate : r      49π = πr²  so : r²= 49     r=7   so : d=14 meters
