Please look up "volume of a cylinder."

The formula for the volume of a cylinder of radius r and height h is

V = pi*r^2*h

So, if r = 1.5 m and h = 10 m, the volume of the tank is

V = pi*(1.5 m)^2*(10 m) = 70.69 cubic meters.

20 pupils can plant 1000 eucalyptus trees in 4hours . Home many trees can 30 pupils plant in 6 hours

Dmitry [639]

Answer:

2250 trees

Step-by-step explanation:

Find how many eucalyptus trees are planted in an hour.

4 hours = 1000

1 hour = 1000 ÷ 4 = 250

20 pupils = 250

1 pupil = 250 ÷ 20 = 12.5 (in an hour)

30 pupils = 12.5 x 30 = 375 trees (in an hour)

6 hours = 375 x 6 = 2250 trees
