Heron's formula
Answer to part 1 = Oblong (ellipsoidal rectangle) Answer to part 2 - possibly egg-shaped? Probably still oblong though.
Half a sphere, which is a 3D shape, is called a hemisphere. The semi-circles in the question is a 2D shape and will make a circle.
if youre talking about a semi circle or a hemisphere, theyre both half circles.
A rectangle or a rhombus.

To find the total length of the fence needed for the track, first calculate the length of the rectangular part. If the width of the rectangle is 32' (the diameter of the semi-circles), then the length is 45'. The perimeter of the rectangle is (2 \times (45 + 32) = 154) feet. The two semi-circles together form a full circle with a diameter of 32', giving a circumference of ( \pi \times 32 \approx 100.53) feet. Therefore, the total length of the fence needed is approximately (154 + 100.53 \approx 254.53) feet.
Yes.
circles, squares, rectangles mainly... but the odd semi circles etc...
Truck drivers like semi-circles!! haha:)

CBs as in CB radios used by drivers of Semi trailers
A rectangle or a rhombus.
Semi circles cannot tessellate on their own because they do not have a consistent straight edge to fit together seamlessly without gaps or overlaps. In order to tessellate, a shape must be able to fill a plane without any overlaps or gaps. However, semi circles can be combined with other shapes to create a tessellation, such as alternating semi circles with squares or triangles.

Calculate the area of a rectangle and of the semicircle separately, then add.
