The answer would be b , because the line is pointing down which makes it a negative slope .
It would be D: 181
3 17
---- = ------
32 X
Then you would cross multiply and divide.
<span>So we want to know the volume V of a cone with a height h=7 mm and of radius r=3 mm rounded to the nearest hundreth. We need the formula for the volume of a cone: V=(1/3)*pi*r^2*h. Now we simply input the numbers and get: V=65.94 mm^2 and that is rounded to the first hundreth.</span>
