A semi-circle is a two dimensional shape.
Two.
pi*a*b where a and b are the lengths of the semi-major and semi-minor axes.
πab, where a and b are the lengths of the semi-major and semi-minor axes, respectively. A=pi*a*b
semi
a semi-circle only has one line of symmetry
a semi-circle only has one line of symmetry
1
None.
Just the one and it is its radius when at right angles to the semi-circle's centre
about its radius
If "cimmey" is meant to be "semi" then the answer is 1. If not, I am sorry, I have no idea.
None, however the semicircle has one folding axis of symmetry perpendicular to the midpoint of the straight side
If the central point of the straight line is placed exactly on the middle, and such central point has an axis, it will have a rotational symmetry.
The semi circle is a shape which has 1 line of symmetry 1straight side 0 equal length sides 0 parallel sides 2 vertices 0 diagnals
Semi means half. So there are two semicircles in a circle.
