Desk weight = d
Bookcase weight = b
b = 34
3d + b = 157
3d + 34 = 157
D = 41
the elm tree would be 6 meter long
since the first cherry tree and elm is 3 meters apart
so this will be 9-3 is equal to 6
This question is asking for the volume of the cone.
The formula is 1/3π r²h where r is radius and h is height.
First we must find the radius by dividing the diameter in half, giving us 3.5
Now we plug our values into the formula like this:
1/3 π r²h
1/3 π3.5² 13
This gives us the answer of 166.76mL or 166.8mL depending on how you want to round it.
Hope this helps :)
Answer: average speed of the train = 4,483.0 km/h
Step-by-step explanation:
Speed = Distance / Time
Distance = 66 km
Time = 15.47 cancelling 15, we have 60 sec added to 47 sec
<u> - 14.54</u>
= 14. 107 60 + 47
<u> - 14. 54</u>
<u> 53secs</u>
53secs to hours becomes =
60 secs = 1 min
60 min= i hour
therefore 53seconds =53/3600=0.0147222hours
Speed= 66/ 0.0147222= 4,483.025
Rounding to 1 dp becomes= 4,483.0 km/h
