The answer is 128 pi in^3. You have to multiply 4x4, then multiply that by 8 to get 128.
2009 - 1894 = 115
That appears to be the same number as
the one that appears in Choice-'B'.
Do you know that multiplicity means the number of times any factor appears in the factored result? Just checking. For example The graph of y = x^2 - 2x + 1 has a multiplicity of 2. they are y = (x - 1) * ( x - 1)
y = x^2 - 3x - 4 has 2 factors.
y = (x - 4)(x + 1) each of the factors has a multiplicity of 1.
So the answer to your question is there are 5 real zeros and 2 complex zeros.
