Find the area of the sector given that the radius
is 4.6 cm and the central angle (Theta) is 2.9 radians.
--------------
Total Area of the circle = (pi)4.6^2
-----
Fraction of the total area that is in that sector = 2.9/(6(pi))
-----------
Area in the sector = [2.9/(6(pi))] * [(pi)4.6^2]
---
= [2.9*4.6*2/6]
----
= 10.227.. sq. cm.
