Answer:
396/π OR 126.05071
———
Why?
To find the circumference of a circle, we use this formula;
C = πd
—> C represents the circumference
and d means the diameter.
Let’s use this formula to figure out the diameter of this circular ground.
396 = πd
Let’s isolate d.
-πd = -396
Now, divide each term by -π to further isolate d.
d = 396/π
You should leave the answer as such. However, if you’re required to give a decimal, make sure you solve using the full form of Pi, not just 3.14 or a couple numbers after the decimal (there should be an option on your calculator) for the most accurate results.
d ≈ 126.05071

Check:
C = 396/π*π
C = 396
