Answer:115.4685yd^3
Step-by-step explanation:
Volume of cone=1/3πr2h
V=1/3×3.142×3.5yd×3.5yd×9yd
V=115.4685yd^3
I’m not sure on this one but what I think you need to graph is the different floors on the Y axis and the time on the X axis. For the time, label it as 1 minute, 1m 30 secs, 2 mins, 2 mins 30 secs and so on. Then you can plot the points. Don’t take my word for this one because I’m not too familiar with these. Sorry I couldn’t be as helpful ~~
Area=length*width
=5*10⁴*6*10³
=5*6*10⁴*10³
=30*10⁷
=3*10⁸ m²
=300 000 000 m²
Do 18 x 9 then u will get get the right answer
