<PRE><B>Question 957842</B>
Convert 52° to radians,leaving your answer in term of pai(22/7).use your answer to find the area of sector of a circle of radius 16cm and angle 52°,giving your answer correct to two significant figures.
----
52 degrees = 52(pi/180) = (13/45)pi radians
------------
Total area of the circle = pi*r^2 = 256pi cm^2
------------
Area of the sector = [(13pi/45)](256pi) = (74pi^2)cm^2
