Question 292225
A rancher in Calgary decides to build a silo inside his corral.
 The rectangular corral measures 22m by 11m and the silo's base is circular with a diameter of x meters. 
Find a polynomial for the remaining area of the corral (in squares meters) after the silo is built.
:
Find the area of the corral: 22 * 11 = 242 sq/m
:
radius of silo = .5x
:
{{{A(x) = 242 - (pi*(.5x)^2)}}}
{{{A(x) = 242 - (pi*.25x^2)}}}
