For answers 17-30 all you need to do is determine the quadrant the points are in. The points are in order of (x,y) , “x” is the horizontal line and “y” is the vertical. (I’m sure you know that) if you don’t know , to the left of (0,0) (where x and y intersect) , all x values are negative, and to the right they are all positive. For “y” the values on top of (0,0) are positive and below (0,0) are negative. So for example, for number 17. (-5,2) the point will be in the top left quadrant because that’s where x is negative (-5) and y is positive (2). Not sure if that’s what you are looking for, you may know all this already but from your question that’s what I assumed you needed help with. Hope this helps! If not sorry.

The volume of this cone is 602.88 cubic inches. What is the radius of this cone?
choli [55]

Answer:

8

Step-by-step explanation:

Volume of a cone formula: V = \pi r^{2} \frac{h}{3}

where,

h is the height             <u>9 in  (assuming)</u>

r is the radius              <u>want</u>

v is the volume           <u> 602.88 cubic inches</u>

\pi is                              <u>a = 3.14 </u>

Plug in everything:

602.88 = 3.14r^{2} (\frac{9}{3} )\\602.88 = 3.14r^{2} (3)\\1808.64 = 28.26r^{2}\\\frac{1808.64}{28.26} = \frac{28.26r^{2}}{28.26} \\r^{2} = 64\\r = \sqrt{64} \\r = 8\\or\\r =-8
