<PRE><B>Question 265849</B>
a rancher decides to build a silo. the rectangle measures 22m by 11m and the silos base is circular with a diameter of x meters. Find a polynomial for the remaining area of the corral after silo is built. 
:
radius = .5x (half the diameter)
:
Remaining area = Rectangle area - silo base area
RA = (22 * 11) - {{{pi*(.5x)^2}}}
:
RA = {{{242 - (pi*.25x^2)}}}
or
RA = 242 - .783958x^2</PRE>
