Question:

Algebra help please re: polynomial thank you (wk4)?

Solve using the five-step problem-solving process. Show all steps necessary to arrive at your solution. A rancher in Beaumont decides to build a silo inside his corral. The rectangular corral measures 20 m by 15 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.

Answer:

Corral area = 20 * 15 = 300 Silo area = (pi)(x/2)^2 Remaining space = 300 - (pi)(x/2)^2
A = 300 - pi(.5x)^2
(Area of corral)-(area of silo) 15*20=300m^2 pi*x^2=area of circle 300-pi*x^2=0 (this is probably the polynomial they're asking for, but i'll solve it further anyway) 300=pi*x^2 sqrt300/pi=x
no one give this child the complete process to solving the equation just guide him or her or they'll never learn
