Answer:
20
Step-by-step explanation:
The area of a circle is equal to pi*radius^2
We can then write this as
314.1592=π*r^2
We then divide pi to get
100=r^2
take the square root and you find that the radius equals around 10
The diameter is always equal to the radius times two which means that the diameter is 20
