Answers have to be more than or equal to 14
Circumerence=2pir or dpi were r=radius and d=diameter
11pi=2pir
divid eobt sides by pi
11=2r
dvide 2
5.5=r
11pi=dpi
divide both sides by pi
11=d
diameter=11in
radius=5.5 in

Answer:
The required equation in standard form is 
Step-by-step explanation:
The equation of a circle with center (h,k) an radius, r units is given by the formula;

The given circle has center (-2,0) and radius squared can be calculated from the given area, which is 


We substitute these values into the formula to obtain;

We simplify to get;
