Mrs. Hellerud bought 18.84 feet of fencing to go around her tree in her front yard. She wants to know the area to find how big o
Lemur [1.5K]

the fencing is the perimeter to the tree, then we can use the formula of the perimeter of a circle to replace this value

\begin{gathered} P=2\times\pi\times r \\ 18.84=2\times\pi\times r \end{gathered}

now we can solve r from the formula to know the radious

\frac{18.84}{2\times\pi}=r

we can use 3.14 to pi

\begin{gathered} r=\frac{18.84}{2\times3.14} \\  \\ r=3 \end{gathered}

the value of the radio is 3 feet

now we can use the formula of the area of the circle to calculate the total area

A=\pi\times r^2

and replace the known value of the radious and pi

\begin{gathered} A=3.14\times3^2 \\  \\ A=28.26 \end{gathered}

<em>the area is 28.26 square feet</em>
