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.

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

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.
add the perimeter of the rectangle, minus the side that'c covered by the semi circle. then, find the circumference of the semi circle [diameter x pi, divided by 2] and addd them together
