Since you did not provide a diagram, I made one for easier reference. You are asking what kind of triangle is the one shaded in red. Since a rectangle has two sets of congruent sides, their diagonals are also equal. When two diagonals intersect each other, they make 4 congruent sides. Thus, the triangle is an isosceles triangle, since it has two equal sides ST and TR.
The formula for the area of a circle is
We know the diameter, and the radius is half of the diameter. So the radius is 9. Now we plug that into the formula.
So the answer is B, 81 pi square feet
