Answer: 3900
ft^3
if you use the formula on how to find the volume of a cone
V=r^2*h/3
you will insert 30 where the r is, 13 in where h is, after you just solve that and your answer would be 3900 ft^3
So... 0.170
0.165.
So at first it was 0.17. But if you add that imaginary 0 its 0.170. So now the answer is 0.170. Hope this helps! ;)
Answer: The answer is 180 degrees
(x - 1)(x - 2)(x + 2)
note that the sum of the coefficients 1 - 1 - 4 + 4 = 0
thus x = 1 is a root and (x - 1 ) is a factor
dividing x³ - x² - 4x + 4 by (x - 1)
x³ - x² - 4x + 4 = (x - 1)(x² - 4 ) (note (x² - 4 ) is a difference of squares )
x³ - x² - 4x + 4 = (x - 1)(x - 2)(x + 2)
(x - 1)(x - 2)(x + 2 ) =0
x - 1 = 0 ⇒ x = 1
x - 2 = 0 ⇒ x = 2
x + 2 = 0 ⇒ x = - 2
solutions are x = 1 or x = ± 2
