You can put this solution on YOUR website! Calculate the area of a sector of a circle with radius 4 km that subtends an angle (5pi/8) Enter your answer in square kilometers?
----
Area of the circle:: pi*4^2 = 16pi
---
Proportion::
sector area/(5pi/8) = circle area/2pi
-------
sector area [5pi/8][16pi/2pi]
----
Ans:: 5 km^2
