Question 1131927
Prove that the area of the minor segment cut off from a circle of radius r cm by a chord c cm from the centre of the circle is given by
1/2[2πcos^(-1)(c/r)r²/180°-2c(r²-c²)^½]
------------
{{{Area = 1/2(2pi*cos^(-1)(c/r)r^2/180°-2c*sqrt(r^2-c^2))}}}
===========
Enter it so that it can be rendered.
Clarify the denominator.
----
Use, eg,  r^2 for r squared, not a squiggle.
