Find the characteristic polynomial and the eigenvalues of the following matrix. If the matrix is diagonalizable, find the diagonalization, i. e., find an invertible matrix P and a diagonal matrix D such that A = PDP-1. (Note: you don't need to compute P-1). A = [1 7 -5 -3 11 -5 -3 7 -1]

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
