Answer:
[tex]Diameter=2\sqrt{256.13} cm[/tex]
Step-by-step explanation:
Area of a circle= [tex]\pi r^2[/tex]
As,
[tex]\pi =\frac{22}{7}=3.14[/tex]
For,
[tex]Area= 804.25cm^2[/tex]
[tex]804.25=\pi r^2[/tex]
[tex]804.25=3.14*r^2\\\\[/tex]
Dividing by '3.14' both sides:
[tex]804.25/3.14=r^2[/tex]
[tex]r^2=256.13\\\\r=\sqrt{256.13} \\[/tex]
Diameter of a circle= 2*r
[tex]Diameter=2\sqrt{256.13} cm[/tex]
