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

• Pre-Cal -

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)
=(49/16)pi
