The question, as posed, makes little sense. All that they would find is the points of intersection of the circles! The question says nothing about the sizes of the circles - whether they are the same or whether they represent some measure of seismic transmissivity of the earth near (under) them.
How can a circle measure 180 degrees? Circles don't have any angles!
Yes because they can be measured mathematically. But free form shapes can't for instance you can't measure a pare using i ruler. But you can measure a square with a ruler.
Pi has undoubtedly contributed to math. Pi can be used for calculating circles and was used to measure distances without doing it the harder way....
Yes. The circles can be of different size. These are called concentric circles.
they use protractors to measure circles
They are circles. We measure circles in degrees.
Protractors have to be half- circles because they measure angles less than 360 degrees.
To use a protractor for circles you find the middle of the circle and you then put the dot on the hole then you measure
Congruent Arcs
Congruent circles, maybe...
Archimedes of Syracuse
For the same reason they chose to measure volume in cubic units
A protractor measures the degree of angles and circles.
same circle or congruent circles
Yes; the circle is a special case of an ellipse.
Congruent arcs are circle segments that have the same angle measure and are in the same or congruent circles.
