The formula for finding the volume of a cylinder is V=πr²h where V is the volume, π is 22/7, r is the radius and, h is the height  or V=1/4πd²h where V is the volume,π=22/7 ,d is the diameter and h is the height.
Given that the diameter is 12 inches and the height is 10 inches, the volume is
V=1/4πd²h
V=1/4*22/7*12*12*10
V=1131 inches³(rounded to nearest ones or unit)
Therefore the volume of the cylindrical container is approximately 1131cm³

If n is an integer, which conjecture is not true about 2n– 1? A. 2n– 1 is odd if n is positive. B. 2n– 1 is always even. C. 2n–
VladimirAG [237]
B.



Let's simply look at each conjecture and determine if it's true or false.



A. 2n– 1 is odd if n is positive: Since n is an integer, 2n will always be even. And an even number minus 1 is always odd. Doesn't matter if n is positive or not. So this conjecture is true.



B. 2n– 1 is always even: Once again, 2n will always be even. So 2n-1 will always be odd. This conjecture is false.



C. 2n– 1 is odd if n is even: 2n is always even, so 2n-1 will always be odd, regardless of what n is. So this conjecture is true.



D. 2n– 1 is always odd: 2n will always be even. So 2n-1 will always be odd. Once again, this conjecture is true.



Of the 4 conjectures above, only conjecture B is false. So the answer is B.
