X^2 - 9x + 18
factors of 18: 1*18, 2*9, 3*6,
the sums of the factors: 19, 11, 9
the positive 18 tells us both factors have the same sign, the negative 9 tells us they are both negative
(x - 3)(x - 6)
Answer:
301.4
Step-by-step explanation:
Volume of a cylinder=pi**h. Assuming you want 3.14 for pi, we can substitue the 4m for r, 6 for h and 3.14 for pi.
V=3.14**6
V=301.44
Since you want to round to nearest tenths, the answer is 301.4
