We have that
<span>Cylinder A has a radius of 2 feet and a height of 4 feet
so
volume of the cylinder A=pi*r</span>²*h-----> pi*2²*4-----> 16*pi ft³
<span>Cylinder B also has a height of 4 feet, but the radius has been doubled
</span>h=4 ft
r=2*2---> 4 ft
so
volume of the cylinder B=pi*r²*h-----> pi*4²*4-----> 64*pi ft³
volume cylinder B/volume cylinder A=64*pi/(16*pi)----> 4
therefore
the answer is the option
<span>C) When the radius is doubled, the resulting volume is 4 times the original volume.</span>
Noooooooooooooooooooooooo
P: the square root of -64 is not 8, but it is 8i. FALSE
q: A triangle has three sides. TRUE
n: 0<0 . FALSE:
s: an obtuse angle measures greater than 90 and less than 180. TRUE
14. p or q TRUE
since it is an OR statement, and q is true, it doesn't matter that p is false.
Since 0.94 is the probability of both devices detecting, the probability of neither doing so is 1-0.94=0.06, answer 3.
The slope is 2/5 or 0.4!
To figure out slope from a graph use the formula y2- y1/ x2- x1
We can substitute the numbers and letters in the formula for the ones on the chart
For example, x1 is -3 because it is the first “x” value on the chart. X2 is 2 because it is the second “x” value on the chart. Y1 is 0 because it is the first “y” value on the chart and y2 is 2 because it is the second “y” value on the chart.
To set up the formula get what is labeled as y2, 2, and subtract it by the y1, 0, that equals 2. Next, get your x2, 2, and subtract it by your x1, -3. The answer being 5.
Turn those calculations into a fraction- 2/5 or 0.4 if you simplify it
If you don’t get it at first don’t worry it takes practice!
