Answer to part 1 = Oblong (ellipsoidal rectangle)
Answer to part 2 - possibly egg-shaped? Probably still oblong though.
The radius is half the diameter.
The circle's diameter
When a circle is folded along its diameter, it creates two congruent halves or semicircles.

A segment across a circle that passes through the center is known as a diameter. It divides the circle into two equal halves, creating two semicircles. The diameter is the longest chord of the circle and is defined as twice the radius.
Its diameter
The radius is half the diameter.
The circle's diameter
The diameter in the line through the circle that defines the 2 semicircles created.
It would divide the circle into two semicircles.
When a circle is folded along its diameter, it creates two congruent halves or semicircles.
Oval = 2 semicircles connected with two parallel lines which are spaced by the diameter of the semicircle. Circumf. = (Pi x 15) + (2*15) = 15 Pi + 30 = 77.124 (to nearest 3rd decimal). Please note that an oval is not an ellipse.

These are chords of a circle. If the chord passes through the centre of the circle it is the longest possible chord, divides the circle into two semicircles and is called a diameter.
There is no single diameter - there are steel rods of different diameters for different uses.
So you have a rectangular field with the two ends semicircles? The rectangular area is 95 yards by 49 yards = 4655 square yards The circular part is pi x diameter squared /4 = 3.14x49x49/4 = 1884.785 sq yds Total area is 1884.785 + 4655 = 6539.785 sq yds At cost of 0.08 per sq yd that is .08 x 6539.785 = $523.18
