The area of the circle above is 1926.5 unit 2 what is the circumference?
Stolb23 [73]

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
