s = rθ
s=arc length
r=radius length
θ= degree measure in radians
this formula shows that arc length depends on both degree measure and the length of the radius
therefore, it is possible to for two arcs to have the same degree measure, but different radius lengths
the circumference of a circle is a good example of an arc length of the whole circle

yes you can still determine the angle measure!
You can't tell the linear dimensions from knowing only the area. There are an infinite number of shapes that all have the same area. Even if you consider only rectangles, there are still an infinite number of different rectangles, all with different lengths and widths, that all have areas of 5,000 acres.
a 45 degree angle is less than a 90 degree angle and more than a 30 degree angle Its like cutting a round Pizza into 8 equal slices, one of the slices is a 45 degree angle, two slices would be a 90 degree angle. 360 degrees is the circle of the whole pizza. It doesn't matter the size of the circle, or Pizza if its easier, the angles will still be the same.
A trapezoid does not have rotational symmetry. Rotational symmetry occurs when a shape can be rotated by a certain angle and still appear the same. In a trapezoid, the angles and side lengths are not equal, so rotating it will result in a different shape. Therefore, a trapezoid does not have rotational symmetry.
You calculate the sqft of the room, a sqft is still a sqft no matter what the tile dimensions are
