Find the area of each circular segment to the nearest tenth, given its central angle, x, and the radius of the circle.
x= pi/8, r=7
find the area of the whole circle pi r^2
multiply that by (central angle)/2pi
In this case:
Atotal = pi (49)
so the area of this fraction of the circle is
[(pi/8)/2pi ]pi (49)
