I have a problem finding the area of this figure on the screen shot. Hope you can help me.
Hi, there are many surfaces...
You want only the value of the area or you want to show the surface ?
Maybe you want the area of the surface between the 2 arcs.
Two ways : with an integral and with a locus
distance(A,B)^2 *(pi/2-1)
a geometric solution with text
.
the 2 CircularArc[] (c and d) has an area and a filling color
the square (poly1) has an area and a filling color
With the text-tool you can calcule with the values of this objects
to show this: double click on the text
show also the Properties/Position of the text-objects
