Answer:
The circumference is 155.49 unit
Step-by-step explanation:
First we need to know the formulas of the area and the perimeter
π = 3.14
a = 1926.5 u²
a = π * r²
p = 2 π * r
First we have to clear the r
a = π * r²
r = √(a * π)
r = √(1926.5 / 3.14)
r = √613.535
r = 24.76
Now that we got r we can calculated the perimeter
p = 2 π * r
p = 2 * 3.14 * 24.76
p = 155.49
