The semi-circle shape can be the 1st or 3rd quarter.
Perhaps you would want to double check, but I believe that if the "flat" side of the shape is facing to the left, that is the 1st quarter; to the right - 3rd quarter.
A week after the Full Moon the Moon looks like a semi circle again, this phase is called ''Third Quarter''
What ? Anything can be smaller than a semi-circle, depending on the size of thesemi-circle. Anything can also be bigger than a semi-circle, if the semi-circle issmall enough. The question is peculiar.
A semi-circle is a two dimensional figure so it can have area but NOT volume. To find the area of a semi-circle see the question below.
First Quarter is when you can see the right half. Waxing Crescent is a crescent on the right side. New Moon is black. Waning Crescent is on the left side. Third quarter is when you see the left half. Waning Gibbous is when the left two thirds to three quarters is visible. Full Moon is the entire moon. Waxing Gibbous is the right two thirds to three quarters.
-- Each meridian joins the north and south poles, making it a semi-circle. -- The center of the circle of which it is a semi is at the center of the Earth, making it a 'great' one. Among parallels of latitude, only the equator is a great circle.
