the fencing is the perimeter to the tree, then we can use the formula of the perimeter of a circle to replace this value
now we can solve r from the formula to know the radious
we can use 3.14 to pi
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
and replace the known value of the radious and pi
<em>the area is 28.26 square feet</em>
