I'm not 100% sure, but I think the answer is 395.6. If you multiply 14 by 9, you get 126, multiply that by 3.14, and you get 395.64, then round it to the nearest tenth, and you get 395.6.
As stated above in the comments ^^
26 is y = 2/3x - 14/3
27 is y = -3x + 11
Let me know if you ever want the explanation! Hope this helps!
Weird problem lol but you multiply 400 times 12 and divide by 200 which tells you he needs to sell at least 24 bikes
Using the Slope Equation
Pick two points on the line and determine their coordinates.
Determine the difference in y-coordinates of these two points (rise).
Determine the difference in x-coordinates for these two points (run).
Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
We know that
[Volume of a cone]=pi*r²*h/3
and
[Volume of a half-sphere]=(4/6)*pi*r³
then
h=14 in
r=9 in
[Volume of a cone]=pi*r²*h/3-------------> pi*9²*14/3------------> 1186.92 in³
[Volume of a half-sphere]=(4/6)*pi*r³--------->(4/6)*pi*9³------> 1526.04 in³
the volume of the prop=1186.92+1526.04--------> 2712.96 -----------> 2713 in³
the answer is 2713 in³
