Question

The area of the circle park is 379.94 feet what is the circumference of the

Answer 1

Step-by-step explanation

We need to apply the equation for a circumference in order to get the needed value, as shown as follows:

`Circumference=2\pi r`

As we don't know the radius, but just the area, we need to isolate it from the surface equation:

`Area=\pi r^2`

Substituting terms:

`379.94=\pi r^2`

Isolating the radius:

`(379.94)/(\pi)=r^2`

Applying the square root to both sides:

`r=\sqrt{(379.94)/(3.14)}=10.9972`

Plugging in the radius into the equation of circumference:

`Circumference=2*3.14*(10.9972)`

Multiplying terms:

`Circumference=69.0624`

In conclusion, the Circumference is equal to 69.06 feet.
