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%28x%29+=+242+-+%28pi%2A%28.5x%29%5E2%29
A%28x%29+=+242+-+%28pi%2A.25x%5E2%29
