A rancher in Calgary decides to build a silo inside his corral. The rectangular corral measures 22 m by 11 m and the silo's base is circular with a diameter of x meters. Find a polynomial for the remaining area of the corral (in square meters) after the silo is built.
.
Remaining area of corral is:
"area of rectangle" - "area of base of silo"
(22*11) - ((pi)(x/2)^2)
242 - .785x^2
.
So, your polynomial is:
242 - .785x^2
where x is the diameter of the silo in meters
